My AT&T iPhone 3GS running iOS 4.2.1 is not currently jailbroken, but that may change now that I know about this. I have a few questions regarding jailbreaking my phone and using biteSMS. I have very important text messages to me that I wish to keep. If I jailbreak, will I have to restore my phone which will then delete my texts? Will restoring my phone at all even delete my texts? Also, if I were to use biteSMS, do the texts also go through the official iPhone SMS aopp? That way, all my texts will be together. Finally, how can I jailbreak my phone? Thank you for your time. If you have any questions, please feel free to ask.
