Unlocked iPhone problem

[NorthernLights]

Guys, I got my unlocked iPhone 2 weeks ago and it's been working perfectly until now.... whenever I try to use one of the applications, for example the iPod, I press the button, the screen then goes black and just returns to the home screen, this happens with SMS too etc etc... What shall I do. Thanks!

If that starts happening you can either....

1. keep pressing that application until springboard crashes and reboots (goes back to unlock screen)

2. switch your phone off and back on.

that type of crash happened alot on my hacked ipod touch (1.1.1)
