To Unlock your iPhone or to upgrade one that is already unlocked, you must first find out what Firmware you are running. Follow the instructions below that apply to you.

Activated iPhone
Its very easy to find the Firmware version on a phone already activated, just touch the Settings button, then General and then About. Scroll down the page to where it says "Version" and jot down what it says.

Unactivated iPhone
Its a bit more difficult to do here. Ok, we are assuming that the iPhone is brand new here as if you just upgraded, you should know what firmware it is.
On the activation screen, slide to make an emergency call, then dial the following:
*3001#12345#*
and hit the call button. This will take you into field test mode, from here, click on "Versions" down the bottom. This will give you some information on the iPhone. It will tell us the Modem Firmware Version and the LCD Panel ID. Use this information to determine what Phone Firmware you are running from the table below.

Sealed (Unopened) iPhone
A typical iPhone Serial number: 7T727XYZWH8
Using the above as an example
- digits 1 to 3 (7T7) = Year / Batch code
- digits 4 to 5 (27) = Week of manufacture
- digits 6 to 8 (XYZ) = Unique identifier part of the S/N
- digits 9 to 11 (WH8) = 8Gb model
You are only interested in digits 4 to 5 which is the week the phone was manufactured and we already know that v1.1.1 started shipping part way through week 39.
If you order a phone online, you can check you invoice online and already see what serial number you are getting before the phone even arrives!
