AT&T said they will unlock my phone only after I have had it for 2 years. I have been an AT&T customer for 4+ years, but I’ve only had this iPhone 4 for 14 months. So they said I have to wait another 10 months, ridiculous. I tried several times and never got anywhere.
So to recap, 2G is for phone service only? 3G will include data plan, and for that I’ll need a China Unicom SIM card? I will need mobile Internet. Thanks again.
