I recently bought a flashed Evo 3d from amazon. The seller had a very high rating and positive feedback, so I figured it wouldn't hurt to try them out. Well, I got the phone, and it took me a couple days to figure out the MDN and MSID had to be changed from the donor's number to my own for the call and texts to work. So somehow I figured THAT out, and I get texts and calls now, but the internet is not working. And I keep getting this annoying popup saying "Data Call Failure - Error Code 67: unable to establish a wireless data connection. if the problem persists please contact your mobile company." So can anyone help me with this internet issue, please??
