So Here's the story...
I have an iPhone 3G , a ton of money(that I don't wish to spend on a new iPhone), not using any sim, am not Unlocked and Jailbroken, and have an interest in iPhone Developing.
I want to upgrade to 4.0 and become a dev, but heres the problem I use an iPhone with no sim I just usually take out my brothers att sim after turning his phone on pop it in my iPhone, and it activated great + att never changed it to an iPhone plan...(However I was told there service was down) I screwed up my iPhone and put it in recovery mode, so I am wondering if I do the process again will it unlock and tell AT&T IF I UPGRADE TO 4.0 OR WILL AT&T ACTIVATE MY IPHONE AND NOT CHANGE THE PLAN TO AN IPHONE PLAN (LIKE IT DID BEFORE) and I don't wanna ever jailbreak again and have no iPhone backup I just need to know if AT&T will switch me to an iPhone plan???
