hey /g/
looking for some help, we're trying to crack the carrier block on my friend's new iPhone 4, because he wants it from Orange but it's on Vodafone

We've tried jailbreaking and using ultrasn0w from cydia, but it didn't work because ultrasn0w isn't up to scratch with the new iPhone 4's base band

anyone know how we can get this done, or at least have any theories or help?

thnks x
