After some debating, I think I'm going to be purchasing an iPhone. That said, I've changed my mind since my last thread (regarding iPhone texting plans). I plan to unlock the phone and keep my existing SIM card. So, although they may be a bit cliche, I have a few questions that I am unclear about...even after researching various threads on MacRumors. 1) I don't plan to sign a two year contract. I am currently on a family plan that includes unlimited texting. If I transfer my SIM card over to the phone, will the unlimited texting transfer over? 2) Since I'm not signing up for a data plan, I assume I will somehow need to disable EDGE services. I've heard of a few ways this is possible. Could someone refer me to the right one? 3) After unlocking, jail breaking, and transferring the SIM, what features on the iPhone will I be missing? I understand visual voicemail will not be possible, but are there any others? 4) Finally, how will this all go over with ATT? Do I need to call customer service to ensure I am not paying any more than I currently am? That's all for now. I appreciate all the help. I feel like I am asking a lot of questions, but understand that (while I know a lot about cell phones) I am oblivious to any iPhone exceptions.
