I got a question, now when i flash my phone and upgrade to 6.5, do I have to call into sprint to get my phone back on the service or does the informtion carry over from the stock rom? I'm a noob @ flashing and since I've been having sooo many problems with my treo pro and been hearing people are having better luck with win 6.5 I figured i'll give it a try, so if anyone can give me some feed back regarding service setup and my question, it would make the holidays much more festive....
