Hi guys, I have an iPhone 4, it is completely jailbroken on iOS 4.3.3 using PwnageTool 18.104.22.168. However, prior to iOS 4.3.3 jailbreak, my brother said (the original owner of the device) he already jailbroke it on iOS 4.3 using Redsn0w and I will not be able to unlock it from O2 as he already updated the baseband of the device. Is there any other way to unlock my iPhone even without using Ultrasn0w? Thanks.

For those iPhone 4 users who are currently locked to O2 who are not fan of jailbreaking the iPhone but want to unlock it so that they can use their device on any carrier, then you will be glad to know that you will be able to unlock your iPhone without using Gevey SIM or Ultrasn0w. All you have to do is fill up this form and wait for the confirmation of O2 people.
