guys,

Apple has gone exclusive with AT&T in the US so in a way the phone is locked even when you buy it from Apple. Pop in a SIM from TMobile and it will not work.

Here are couple of advantages of doing the unlock:

1. You can install third party applications (well it is a byproduct of the unlock)
2. You can stay with AT&T without extending your contract to another 2 years.
3. You can use your TMobile SIM with no contract renewal
4. You can travel abroad and use any other GSM network/SIM and not pay AT&T the roaming charges.

Disadvantages:

1. You would have to restore back using iTunes if you need warranty work on the iPhone
2. You lose visual voice mail (it is being worked on right now so a fix might be possible)
3. Phone can get locked again if Apple/ATT sends out a new radio firmware via iTunes. Best is not to upgrade iTunes till you hear from the hacker club saying it is ok to do so.

The Unlock will not:

1. Make you better in bed.
2. Give your phone another 5 HP or better 0-60.


hope this helps.
