I just sold my iPhone a couple days ago to an ATT goPhone user. After I reset it using the erase all feature under settings the phone was only able to make emergency calls. I plugged it into my computer to activate it. After that the new user was able to plug their ATT sim into the phone and it worked just fine. My question is, since I synced it with iTunes before selling it, will I have any ties to the phone? Will this prevent me in any way from getting another iPhone? Anything in general I should be concerned about? I'm probably being paranoid, but I appreciate the help.
