So last night I finally jailbroke my 3G iPhone. I messed around with some themes using Winterboard and just sort of customized the phones layout. It looks cool and works fine, but everytime I try to open the basic "Phone" app, the app opens but the phone freezes and goes back to the home screen. I can still get incoming calls and I have no problem with texting. I spent some time googling for anyone else with this situation to no avail. Any help? Thanks.
