How do you unlock an iPhone 3G?
To unlock I-phone 3G there are many ways available …I would suggest the site Theunlockspot.com get remote unlock service and unlock it easily.
Apple will NOT unlock the iPhone for you they have exclusive deal with O2. you do NOT need to unlock if wanting to use it with an O2 PAYG SIM or contract SIM only other carriers SIM’s. iphones on other networks will NOT have the internet access ability as thats only with contract phones with the 3G /EDGE browsing and the WiFI sign ins for BT openzone or the cloud. you can buy SIM overlays for the iphone 3G from the uSA but these might only work with the US AT&T netorwks SIMS best ask the makers to check. NEVER NEVER JAILBREAK! It causes so many problems and yet adds nearly nothing! the 2.0.1 software form apple is stable and works well and lets you add hundreds of apps (many free) from the itunes App Store. Jail breaking became redundant when the 2.0 software was released as it add almost nothing to the ipods abilities (other than the ability to browse its file structure which also makes it less secure). Jail breaking also voids the warranty and does cause many issues form files vanish
