Have tried everything - please help :(
Let me start this post by saying I have tried everywhere to find an answer or help for this.
I am in the UK. My father gave me his Iphone 3 as he had just upgraded to the 4. I knew I would need to have it unlocked but what a saga it has become.
I gave the phone to a friend to jailbreak and unlock for me. He gave it back saying it hadn't work but when I received it I noticed the following:
1. Cydia was installed
2. My carrier used to say TELUS CANADA but now says VODAPHONE UK 8.0 and now appears to be locked by Vodaphone?
3. My version is 4.1 and my baseband is 6.15.
After research I see my friend has upgraded to the 6.15 which isn't ideal but everything I read has said ultrasn0w should unlock my phone. I have successfully installed it several times but when I put my Tesco Sim in the phone (which Tesco say should work) I only get NO SERVICE and under Carrier it still shows VODAPHONE.
Anybody? Please?????? I'M DESPERATE!
