No Data Connection - already replaced SIM
Ok, here's the deal. I bought a slightly used AT&T SGS II from a friend of mine. I rooted it (no custom ROM). At this point I noticed that I was getting no data connection. I did not notice if it worked before I rooted. I went to the AT&T store and got a new SIM card, which didn't help. My old SIM, and now the new one, both work for data in a Captivate and an Atrix. Looking for any ideas...
