Do a hard reset and see if that helps. Hold home and power buttons down at same time until the apple appears, then release.

2 Questions:

1. What firmware are you on?
2. Are you jailbroken?

I had some BIG trouble on my V1 JB 2.0. Many of both AppStore and Cydia/Installer apps was crashing often. I would try an restore..
