Iphone 2.2.1 / 2.30.03 unlock

Just wondering if anyone has seen any updates on locking this?

 

ZMonkey:

My iPhone is locked to Optus Australia. Will Gevey 3G Sim Card unlock it completely so I can use it with Virgin Mobile as a carrier?

I have tried all these so called hacks with Jailbreaking my iPhone 2.2.1 with Firmware of 02.30.03 and am still locked to Optus.

Is it possible i could go back to 5.08 bootloader, and if so how do I do that. I want to unlock my iphone to work with T-mobile
