You will need to change the apn for the data in the network settings to att.mvnoWell...that's responses from 2 I trust. So the answer is...any Iphone, any iOS, any baseband will have talk, text, data by using a H20 sim and activating on H20s $60 Unlimited Plan. If MMS is wanted, a jailbreak is required in order to access the cellular data network tab so you can change the APNs.
Thanks guys and happy selling.
