Ok currently I have an old nonsmartphone from Tmobile, which is my carrier. I want an iphone, but I can't switch to a carrier who has the iphone. So I want to buy an iphone that can be unlocked to be used for Tmobile, is that correct? If I were to do this what firmware iphone should I buy to be able to do this? I want the iphone 4, so I'd probably be buying it used online.
Also, if i cut my tombile sim card to fit the iphone 4, I can call normally correct? I won't be able to pay extra monthly for data, so could I use the iphone for just calling and wifi for all my extra stuff? I currently do not have text on my plan right now, but if I added it... how will it work on the iphone? I currently text on my 1st gen ipod touch with a texting app in which i need wifi to receive and send texts.
Thanks!
