Currently there is a conversation open in my sms app. When I try to press back to gotothe main page to view all conversations, SMS crashes. Even after rebooting i cant get back to that screen. Any ideas? Edit: I'm not sure if it will help, but if anyone has the sms app they can upload for me id like to try replacing( it. I'm on an iphone 3g running os 4.0 jailbroken.
