whats the best unlock

new to the site but i do have an unlocked tmobile iphone with everything working which my buddy did for me. but i was wondering if some one can post the best unlock apps step by step how to unlock the iphone with links and a site we can all use to redownload the filmware and the itunes that work just incase we get our phone locked back we can get a step by step with the best programs that work along with the filmware and itunes that will work with it. im sure well all would appriciate it. also the new filmware wont sync on its own will it? i would think that you would have to agree to download it but not sure help. thank you

I hate when people say that to me. But sometimes its the right thing to do.
