Something I installed has my phone randomly restarting... It works until I click on Rock or Cydia, and will only restart sometimes. Sometimes it will also restart without clicking on one of those, but simply on the springboard.

I have restored 4 times so please don't suggest that. Does anyone know of any buggy apps over the last few weeks? Or any other fixes, so that I don't restore, reinstall my apps with Rock and then have to restore again. Tx
