App store app crashing on me iPhone 4?

[RCizzle65]

Whenever I try to open it, the categories stuff pops up on the bottom, and it says its loading, but then it just jumps me back to the home screen. This happens most of the time, but once it successfully opens, it's fine if I don't take it off of multitasking.

I am having similiar issues when it should prompt for the password.
