Hello everyone. I'm overseas (not in the US) for a few months and I'd really like to unlock my iPhone to use the local phone carriers. I'm currently still in contract with ATT. I contacted them to request for an unlock but since my 2-year period is not up, they refused to do so. I know I could always use the other online services like unlock fusion on eBay or something. But, I'm wondering what are the consequences of doing so? For example, 1. Will my iPhone still work with ATT when I pop back the ATT sim card? 2. Is it illegal to unlock my phone without the consent of ATT? Can they take any action if I unlock my phone? and if so, is there anyway to reverse the unlock process so that they won't know? 3. Will unlocking my phone void any phone warranty? Or cause any issues with my contract with ATT? 4. Will it negatively affect the programming in my phone or something? That's the few questions I have for now. Any comments will be much appreciated!
