Look at Opera Mobile 12 stealing Chrome Mobile’s & Firefox Mobile’s thunder:
And while there’s more to browsers then just HTML5-support, Opera Mobile 12 also seems to offer greater support for modern web technology features than IE9.
I’m on the beta-release channel for both my desktop and mobile Firefox and my desktop has been running version 11 (with SPDY) for over a week now, but there hasn’t been an update for Firefox Mobile Beta in the Android Market yet. Apparently the Mozillians are working hard to finish the complete overhaul of the front-end, which integrates with Android UI (instead of using Mozilla’s own XUL) and services (synchronization in particular).
Mozilla is doing a great job in the mobile space, with the browser, but also with WebAPI and B2G. No, I don’t think I’ll switch to Chrome Mobile any time soon.
