I got a Samsung Galaxy S II Skyrocket last night to replace my iPhone 3G. From the intructions that I found, I put in the battery, a memory card and the sim card from my iPhone and then let the phone fully charge before turning it on. From that moment to now everything has worked just fine except I have yet to get an internet connection unless I'm on wifi. My family is on the old unlimited data plan so I don't know what the problem is unless I activated it wrong? Thanks for the help!
