I'm at my wits end with my 2nd Captivate. I returned the first one 2 weeks after purchase when it started to randomly shutdown. Then all was well for 2+ months and now my 2nd phone is starting to shut down randomly. To add insult to injury, after the latest OTA the phone is locking up, crashing the email app and freezing the messaging app. Sometimes I have to reboot just get email to start syncing again. Worse still, with Exchange PIN security enabled, the phone doesnt always accept the Enter/OK keypress after putting in the PIN so i'm stuck at the unlock screen. 100% stock never-rooted phone and no funky apps. I can't rely on this phone anymore, plus Exchange support is still mediocre. What do I do at this point? Exchange it for another unit? Wait for Froyo? Wait for WP7 phones? ATT has nothing that comes even close in terms of HW features. I came from a Samsung Blackjack 1, then 2, then Jack and all were great phones. This is such a letdown from Samsung.
