If you are an iPhone 3G owner and were looking to unlock your device after jailbreaking iOS 4, then your wait is over!
According to the Dev Team, redsn0w beta has been updated and now it has the ability to hacktivate or unlock your phone that will allow your phone to work with any SIM provider.
The best thing about this release is that not only you jailbreak you iPhone 3G, but also you can unlock it at the same time. Previously we saw loads of unofficial pwnage tool bundles flowing in that actually caused more harm than good.
