Ok so I have a jailbreaked iPhone and I use installer to get all the third party apps and I have the app that lets you type any thing you want for where the at&t logo is so I first changed it to iBaxter (my last name) then I wanted to change it and so I clicked on it and then i started to go crazy and my phone kept flashing like black and white lines and stuff i turned the phone on and off but still nothing as soon as i turned it on it would start doing the same thing I have restored it and it now works.

Does any body know what happend i got the app from erica's utilities...
