help on unlocking

[nyr99]

Hello.

I currently have a 8gb 1.1.3 jailbroken iPhone on ATT. my sister wants to buy it from me for $200 when i buy the 3g. She has T-Mobile.

What will be the easiest way to unlock the phone. I would like to restore the phone first.

Also, after i get it unlocked, how will her service work with it. she does have a data plan so will the internet work as it does with ATT? Also, will youtube work?

Thanks a lot.

You should be able to find "Unlock" in the Installer. Install that and she should be set. Concerning the data, make sure her plan is unlimited or she'll get screwed big time. Yes, YouTube will work.
