Browser:	BOLT 0.94	Teashark beta 0.9 build 419	UCWEB 6.3	OM 4.2
Operating system compliance: BlackBerry	+	-	- (and they don’t plan a BB-compliant version either)	+
Windows Mobile touchscreen (Professional) without a dialpad / keyboard	+	- (while it does run, the touchscreen can’t be used; that is, completely useless unless you have a phone with a numeric dialpad or a keyboard to enter URL’s)	+ (with a native version; note that going to wap.ucweb.com will result in your getting the inferior Java version! The native WinMo version must be downloaded HERE – note that the page, otherwise, accessible from the general download address, only has the Chinese version. Alternatively, from the English page, you can follow the Dopod link, then, p, and, finally, for example p6500 [direct link; get the uppermost file, it's the latest version])	+
Windows Mobile touchscreen with a hardware keyboard	+	+ (note that the non-native, inline text input fields may not make use of the hardware keyboard at all or fully [on the HTC Universal, for example, it's not possible to enter / on them]. To fix this, you can press the left softkey while in them (for example, in the Enter URL field) and just select Edit. This will take you to the standard editor of the midlet manager already with keyboard support)	+	+
Windows Mobile no-touchscreen (Standard) with a dialpad (and possibly a keyboard in addition)	Partial: not all keyboards work; for example, that of the HTC s710 / Vox MS smartphone doesn’t work with the address input field and you can’t switch to the system-level one, unlike on a touchscreen-enabled Pocket PC. That is, you’ll need to use the dialpad to enter text.	+ (also see the above remarks on keyboard usage with inline text input fields)	+	+
Symbian S60	+	+ (albeit, on my N95, it has never got past of the initial initialization)	+ (even native SISX file – this also means no mobile connectivity icon in the upper left corner, unlike with OM / BOLT. Not that it’d be that important: the Symbian version doesn’t seem to have a Full Screen mode [unlike Java: Settings / General Settings / Full Screen]; that is, no active content would be hidden by this icon.)	+
Signed versions? If there are, compatibility:	BB: -; WinMo, Symbian: +. WinMo: dual-signed tested with Esmertec Jeodek 20070425.1.1, Jbed 20070802.2.1, 20081203.2.1 and 20090217.5.1R2; all worked great. Symbian: the same (note that, there, you’ll need to set “Always allowed” in Applications / App Mgr. / [Action on BOLT] / Open)	-	-	BB: -. By default, WinMo is also -; Symbian: + (must manually make sure,in AppMgr, connectivity is set to Always, though). For WinMo, you MUST go to http://operamini.com from your built-in Internet Explorer Mobile and select the "If this version fails..." link (selected HERE). Then, just get the first version with the multiple certificates (selected HERE). Note that you shouldn't use Internet Explorer Mobile 6 (see for example THIS for more info) for this; Opera's Web server won't recognize it as a WinMo web browser and, consequently, you'll be taken to the desktop version of the Opera Mini pages, where you will only have access to the unsigned version. The WinMo certficates work just great under Jbed.
Layout: Original (non-one column) layout?	+ (default mode)	+ (works great)	- (the biggest omission) on Java, + on Symbian / WM (Zoom mode – the default is the “Adaptive”, that is, one column mode; you can switch via Settings / Browse Mode)	+
One-column layout mode?	-	-	+ (the default on Symbian / WM; there’s no original layout on Java)	+
If original layout is supported, dynamic zoom in/out from text reading?	- (the shared screen can’t really match the zooming of Opera Mini)	+	+ (Symbian / WM only!)	+ (in the default, non-One Column mode)
…quality of text reflowing?	In cases, highly inferior to OM or Teashark – must use far smaller chars to avoid having to horizontally scroll – even with Mobile View enabled	In general, excellent – much-much better than that of UCWEB	Poor to acceptable (MUCH worse than that of OM or TeaShark): with DPReview, problems with quoted text and one-row messages; with the official UCWEB forum, no user post reflowing at all. The PPCMag blogs aren’t rendered at all (Symbian screenshot of the same). (Symbian / WM only!).	In general, excellent: works just great in non-one column mode with most sites; if it doesn’t, then, One column helps this.
…does it try to keep the horizontal alignment while vertical finger scrolling (see explanation HERE)?	-	n/a (absolutely no touchscreen scrolling)	+ (only tested under WM; I couldn’t test this on Symbian because I don’t have a touchscreen S60 model – yet)	+
…speed of horizontal positioning to the text	Using the D-pad / scrollbar / dialpad, much faster than previous builds. Definitely faster on devices with a touchscreen – and under Opera Mini, though.	Very fast: roughly as good as Opera Mini	Pretty fast even with buttons only	+: generally, it only takes 2-3 quick button presses to quickly zoom into text and position to the text body
Scrolling: Quick positioning to top/bottom	BlackBerry: + (T/B, respectively); WinMo: - (not even the hardware keyboard works – except for the numeric keys)	-	- (on touchscreen-enabled devices, however, you can quickly scroll up/down)	+ (repeatedly pressing #3 – or simulating it with an assigned hotkey)
(Touchscreen devices): Scrollable scrollbar	-	n/a (no touchscreen support)	+ (scrollbar size can be set in the Java version, unlike with OM or the Symbian / WM ones)	+ (they take up quite a lot of screen estate, though)
Real rubberband & inertia on touchscreen devices (see explanation HERE)?	-	+ (very nice-looking; of course, this only applies to D-pad / numeric keypad-based scrolling)	- (Java) / + (WM)	-
Character sets: VGA WinMo devices: maximal charsize (see the reason for this HERE) running under THIS hacked Jbed - or any newer Jbed version (starting with 09/2008) with the fontsize registry hack applied	It uses its own charset independent of the system charsize; therefore, 3XLarge is still smaller than OM’s or UCWEB’s	n/a (if you still want to use it: it only has one character size; it’s very small on VGA devices)	Definitely bigger than BOLT’s	Definitely bigger than BOLT’s
Quality of custom charset: readability vs. (small) size	Better than OM	n/a (one character size only)	n/a (uses system fonts only)	Slightly worse than BOLT
Bold / italic / underline	- / - / +	+ / + / -	Symbian / WM: +/+/- ; Java: -/-/- (very poor). Slight rendering problems under WM (but not Symbian): no spaces are rendered between two differently styled words.	+ / - / +
Sub / superscript	+ / +	+ / +	-/- (all the three versions)	+ / +
Displaying different charsizes	Two or three	Two (“small” isn’t rendered smaller) – screenshots: 1 2 3	Symbian: three (with default charsize of 16; only H6 is rendered as small, nothing else; screenshots: 1 2 3); WM: one (screenshots: 1 2); Java: one (screenshot)	Three
Internationalization support	-: As it uses its own characters, the size settings are more dynamic but no support for non-Western languages at any charsize	+ (it uses the system fonts)	+ (it uses the system fonts)	+: It relies on the system characters, except for the small charset. No Western support in the latter.
Multimedia: support for Web videos?	+ (transcodes to 3gp and relies on a local player to play it back; currently, up to 1:30 minutes. Works on all the listed platforms out of the box, except for WM Classic, where a 3gp-capable player needs to be installed)	-	- (YouTube isn’t supported at all in any of the versions; complains of lack of Flash / JavaScript support)	-
Multitabs: does it support keeping more than one page in memory?	- (no in-memory caching at all – bad!)	+ (albeit definitely fewer pages than UCWEB or Opera Mini)	+	+ (depends on size; in general, up to 30)
(For touchscreen users:) On-screen tabs for quick switching?	n/a	n/a	+ (in Java, you can even select their size: when minimized, they’re only a pixel high but still clickable. In WM, you can’t achieve this by switching to full screen mode. Under Symbian, no unnecessary [unclickable] tabs take up the screen estate)	- (takes quite a few clicks to switch documents if you don’t use keyboard hacks:
(For dialpad users:) Shortcut for quick switching between pages?	n/a	+: page switching is very easy: just press the right softkey (or 7) and, then, scroll between the thumbnails. Too bad they only show the top left corner of the page (as with the dynamic page view in the upper frame), which may be an issue if you want to find a specific page from a server you’ve opened several pages from, being not necessarily different in this uppermost area (like the PPCMag blogs)	+	+ (#5 to access the document list)
Does it force the user to reload pages upon pressing Back?	+	-	-	-
Can you directly tell the browser to open a new page in a (background) new window (tab)?	n/a	n/a (it, by default, opens everything in new tabs. Note that, if you select [but don’ activate] a link and press 1 to bring up the context menu, you’ll also be able to open it in the 2nd tab [and vice versa, in the first]. This, however, only allows for two open pages at a time – unlike he default, “just activate a link” approach)	+ (after highlighting / selecting a link, both New tab and Background new tab – excellent!)	-: all you can do with a link (through the context menu’s [1 / long tap], Link) is opening the page (selectably with images) and showing the address without copying capabilities (albeit switching back to the previous page is pretty easy, particularly if you have a hardware dialpad)
Closing unwanted tabs	n/a	-	Under Symbian and Java, excellent: Close current (with shortcut “C” on Symbian) / Close Others. Under WM, Close Others isn’t available	- (tabs can only be automatically discarded from memory)
Copy from current page: Entire document?	-	Teashark has probably the best way of copying text from a page. Press 1, select anything except the first (“Open link in 2nd/1st tab”) menu item [Google for…, Wikipedia this… Definition of or Call this number…). Then, go to the first section of the text to be selected, press Action, highlight the stuff you want and press left softkey (Menu). Then, select Edit; now, you’ll be in the midlet manager’s own text editor, with copying capabilities.	+ (note that after selecting anything to copy, you’ll need to go to Clipboard Manager [Menu / Tools / Clipboard or #3]; it’s only there that you can directly edit the previously copied texts and select / copy anything you want)	-
Current viewport only?	-	See above	+	-
Selected link?	-	See above	+	- (you can, however, follow the link and, then, edit the then-current address to get the link)
Address of selected image?	-	-	+	-
Misc: Find in page	+	+ (even supports Previous)	+ in Symbian / Java; - in WM. (under Symbian, there’s also a “Find Next” [in addition to “Find in page”] in the Tools menu, NOT under Java – in that, you can in no way find the next occurrence, unlike with Bolt / OM)	+
User-agent redefining:	- (hope this will be implemented – after all, Thunderhawk did support this)	-	+ under Java (Empty / Phone default U-A / Openwave / Opera), - under Symbian or WM (there, under “Network”, only the default access point or the connection group can be set)	-
Keyboard / dialpad key shortcuts	+	+ (not many though and can’t be redefined, unlike with UCWEB)	Under Symbian / Java (but not WM): Excellent, even redefinable (screenshots of the accessible methods: Java; Symbian: 1 2 3 4 5 6 7 8 [note that I haven’t made a screenshot of all of the dialog pages!])	+
Download manager?	-; uses the external browser (on WinMo, for example, Internet Explorer Mobile) to download. That is, downloading can run in the background	-: see remarks with BOLT	+ (excellent, you can set a lot of parameters in the two native versions [Symbian screenshot of the same]– but not in the Java one [screenshot of Settings]. Nevertheless, the latter is also pretty nice.)	-; can both use an external browser (e.g., Internet Explorer Mobile) for downloading; however, you can also select downloading inside Opera Mini itself
W3C test results	good	Fair	really poor (Symbian; WM; no Java screenshot as it doesn't at all support non-one column views, which further worsens the results.). For example, unlike with the three other browsers, the JavaScript links on the left of DPReview can’t be invoked at all.	good
Image zoom to see images at their original resolution / quality (not at the dumbed-down, downsampled one)	-	-	+	- (only if you save them and read back from the file system)
Favorite synchronization	-	-	- (albeit you can export / import your favorites in the Symbian [but not the Java!] version)	+ (Opera Link; can be – manually – synced even with non-Opera desktop browsers)
