I have a Samsung Galaxy S2 from straight talk. I rooted the phone to ATT i777 4.1.2. It worked great for a while. Then started freezing up all of the time. So I rooted to 4.2.2 today. I have the ability to make calls and text, but no data. I've tried every APN setting I could find and tried chatting with straight talk support but no luck. Any ideas on what I could try to get my data working? Data is enabled.
