Stupid questions.

Have 1.1.2 unlocked and jailbroke. In addition to having the 19.99 total internet plan.

Is it possible to update 1.1.3? If so, i am assuming just follow the Jailbreak guide.

Has anyone experienced issues upgrading to 1.1.3 w/ tmobile? Are the new features worth it?

Will my edge network stay?

Any suggestions?
