Alright, I'm sure this has already been asked, but I've searched around and can't find a definite answer. I have a newer iPhone 3gs that I received via a free upgrade with AT&T in November, 2011. My question is whether or not it can be jailbroken? The model number is MX640LL and the serial is xx144xxxxxx It's updated to the latest software 5.1.1. I'm nervous about jailbreaking already then I read it's possible some versions of the 3gs could end up bricked. Waah If anyone could give me some insight it would be much appreciated!! <3 Clearly I've never jailbroken any other devices before.. .
