Techincal iPhone carrier locking query...

[Detroit_Waves]

So here is a question related to another post I had made.

I bought my iPhone in the US, as I spend half my time there, so upgraded with AT&T, and got my iPhone 4 there. When I came I was having proximity issues, so took it for a replacement with apple. Upon which they told me it would be unlocked to any network. Fantastic...meant I could use it with my O2 contract...so got an o2 mini sim.

I put the sim in today, nothing happened...so plugged it into Itunes, upon which it told me it wasnt a correct sim, and I needed to put the sim in that I had registered the phone with...and when I put in my AT&T one, it worked fine. Thing is I had never registered my sim with this new phone from apple, and it appears to not be unlocked and it wont accept my o2 one.

Whats going on?

Apple told you wrong when it was replaced - they said the same to me when I replaced my O2 iPhone 3GS which was already unlocked via O2. I had to re-request my unlock from O2 on the replacement iPhone...

I guess its something to do with iTunes/Apple ID and how you originally purchased the phone - in your case your replacement has been 'told' to be locked to AT&T...

Hopefully though for your sake Im totally wrong! The way an iPhone unlocks seems to be totally different to a normal phone unlock...
