I had the same problem earlier (using yesterday's firmware, not today's official firmware). My phone was acting sluggish, so I restarted it. Upon restart, I got the connect to itunes screen! I did a hard reset, and my phone restarted fine, but 3 of my apps (holdem, monkey ball, and the dice poker game) would show the first screen then crash. I turned my phone off and left it off for 5 minutes (to drain the capacitors) and that fixed the problem.
I bought a few apps on my old iPhone yesterday. I bought an iPhone 3g today. I finally got it working, but none of my apps will launch. They show the opening screen, then kick me back to the home screen.
Is anyone else having this problem?
everyone should open iTunes, click on the store pannel (up by file, edit ect) press authorize computer!
then delete the apps manually off of the phone, re-sync them from your computer to the phone.
that SHOULD cure it. I had the same problem when i first got the phone. It got to the point where i did not sync ANY of my apps, and only kept them/and downloaded them unto the phone. Doing that allowed the apps to work. However, doing the authorization aswell as the delete/resync should cure all of the issues.
