Hi all - My contact is up June 21st and since AT&T determines unlocks by contract and by device, my 4S is eligible for unlock then. (Bought with my mother's account and then we swapped sims/phones) I was going to take it to Virgin Mobile, but apparently cannot due to the CDMA antenna being disabled in the phones carried by GSM providers, so I was thinking of taking it to AT&T's prepaid. Couple of questions: Do they officially support this? Can I get data under their "unlimited data" plan? The rep said I could, but they're well, you know. If I get data via them, can I use built-in tethering with it, or is there a PAYG tether option? DOES VISUAL VOICEMAIL WORK!? Thanks in advance!
