Heya people! I'm on contract with O2 and have regualer updates on my computer with the iPhone. I was wondering. I only want to jailbreak the iPhone, to put themes on there. Cause I'm bored of the ones that are on there. If I jailbreak the iPhone. Can I still get firmware updates and all that? Like, will Apple/O2 know and all that. I want to be able to still update the phone and all that lergitally and not be able to get like locked out or something! Thank You!
