I currently have a Blackberry 8320 on T-Mobile. I'm looking to jailbreak an iPhone to keep my t-mobile service, but I have some questions. 1. Can I still use Apple apps? I read that you can't update the software because it will undo the jailbreakage, but I don't know about apps. 2. What service plan would I use from T-Mobile? Just a general so-many-minutes a month? Or would I also need a data/internet plan? 3. Any massive drawbacks from having a hacked phone that I should know about? In other words, is it worth it or should I just pay the million dollars for AT&T?
