Opera Mobile: changes in version 8.6, compared to betas	MUCH faster than the beta when downloading to a card. Now, it's the fastest browser at one-threaded downloading in general.
PIE/IEM: changes in the WM5 version, compared to pre-WM5 (for example, WM2003(SE)) versions	The download-to-card algorithm has been made much more efficient & faster on most WM5 devices by internal storage-based, safe (!) buffering. Kudos to Microsoft for listening to me and my past complaints about slow download speeds.
