Hello,

I was wondering if anyone could confirm if a US iPhone with software version 1.1.1 (the latest) would work unaltered with a UK O2 sim card.

Thanks in advance!

Okay, is the firmware completely different?
Would it be possible to flash a US iPhone to the UK firmware?

Have you tried inserting a O2 sim card in a US iPhone version 1.1.1?

Thanks

The us phone is locked to AT&T carrier, so youd need to unlock it to use 02 uk sim. don't know about flashing the firmware, might work.

Okay. I just wondered if the software version 1.1.1 would include a lock to AT&T and O2 only as we are now very close to the UK launch on the O2 network.
