5 Reasons Not to Jailbreak IPhone 5

Bricking

As with any tampering of your iPhone, you run the risk of experiencing "bricking." Bricking renders your phone unusable and requires a complete wipe and restore to make it functional again. Not a big deal given the quick fix, but it does serve as a deterrent.

5 Reasons to Jailbreak IPhone

Access to T-Mobile GSM Network

The biggest problem with the iPhone is not the "death grip" that blocks your mobile signal -- it's AT&T. AT&T has exclusive rights over the iPhone until at least 2012, and with all of the network's problems -- mostly related to its tendency to drop calls -- many are justifiably wary of purchasing a phone tied to a problematic network. But the latest jailbreak gives users access to T-Mobile's GSM network, which works overseas and may be more robust in your area.

 

IPhone Activation

The iPhone normally prevents access to its media player and web features unless it has also been activated as a phone with an authorized carrier. On July 3, 2007, Jon Lech Johansen reported on his blog that he had successfully bypassed this requirement and unlocked the iPhone's other features with a combination of custom software and modification of the iTunes binary. He published the software and offsets for others to use.
