OK all I want to do is buy my iPhone from Apple.com unlock it so I can use my t-mobile sim, unlock it so I can add 3rd party apps, and possible get 1.1.3 update but most important is unlocking it to use with t-mobile sim. Lately I've being getting so confused by all the topics I've read. I need someone to confirm that I can do all of the above if not just time exactly what I need to do to aleast sim unlock it, so I can avoid buying a whole unlocked iPhone from ebay. I want to do it myself. Please help me!
