Hi have done that several times, phone is locked to Telus from canada and i'm in Australia, spoke to Telus and they said they can't unlock. I think my problem is that the the baseband 4.11.08 can't be unlocked.

I have iphone 4 running ios5 (9A334) basband 04.11.08 I have jailbreaked iphone using Redsnow, has jailbreaked, but has not unlocked, as still says No Service, I must be missing something, can people please offer advice
