I've bought a second hand iPhone 4 off of ebay to use out here in Germany. I've got my T-Mobile microsim installed, but it appears the phone is locked.
The phone was on Vodafone, but as I don't have an account with them they won't unlock it, and T-Mobile won't out here as it's not their phone.
I've read some articles on jailbreak and unlock, but then it got talking about things I've never heard of...
Anyone here able to help?
