After a few days with 3.0 i've found that most of the apps work quite well. At first i tried the "restore from backup" option when setting up 3.0 This was not a good choice. Consequently, i had issues with: - YouTube - would launch, then abruptly crash - Voice Memos - would launch and then freeze iPhone, requiring restart - Phone - UI would disappear mid-call, freeze iphone, or not let me dial - Palringo - would launch, then crash at login - Pandora - would not launch - EleMints - would not launch - iPod - would launch and crash before showing me my library, corrupted my music database - Search - results would not appear, would tremendously slow down iPhone - Audio - delayed, or none at all - Speaker Hiss - speakers would crackle and hiss even when volume was all the way down - Keyboard - laggy beyond usability After setting my iPhone up as a new device, all of the above problems were either fixed or ameliorated. App Compatability/Issues: - Photos - once zoomed in you cannot move your picture around - Tweetie - some UI lag, lots of lag when taking picture for direct post to twitter - Facebook - some UI issues, will not load any pictures - Remote - no issues - Voice Memos - lag - Pandora - no issues - Tetris - some lag, works fine - Rolando - longer loading time, works fine - DDR - some UI issues, does not play music along with arrows (voice commentary is still there which is odd) - Ambiance (2) - crashes at splash screen - Palringo - no issues - Bank of America - some UI issues, won't remember my device - EleMints - faster than on 2.2.1! - EN-RU Dictionary - crashes upon database initialization - WordBook - crashes while searching for word, (5-10s after launching) - Translator - no issues - Wikipanion - no issues - Dictionaire - very laggy - Pocket Guitar - no issues - Loopt - no issues - Urban Spoon - no issues overall I'm happy with 3.0, with all the beta-testers, hopefully the next release will be significantly better. Please Post Your findings!
