I bought a iPhone yesterday and I want to know how to unlock it so a T-Mobile simcard can work. I want like youtube and stuff to work too. I have wifi in my house if that helps.

Also will the $5.99 tmobile internet work with the iphones?

You cant. apple made the iphone so the sim card cant be taken out... way to go, you are either gonna have to switch to cingular or use the iphone without the phone part.... which i think means without the internet too. Maybe you should have looked into that BEFORE you dropped a bunch of money into it.
