Are we going to have to update ALL of our apps/games from now until the new 3.0 update is released? This may have been answered somewhere else but I haven't heard. So far I have had to update SonicVox(Smule), Ocarina(Smule), and Crazy Snowboard(Ezone.com) which say, for the version number, "Tested under iPhone OS 3.0". So does anybody know for sure the answer to this?
The recent apps have all been reviewed for OS 3.0 compatibility. http://www.macrumors.com/2009/05/07/app-store-submissions-now-being-reviewed-for-iphone-os-3-0-compatibility/ Your older apps should be fine as well. Apple has built 3.0 to handle older 2.x apps.
