Thread: Please help iPhone sim transfering for jailbreak?

Ok basicly I have a 3gs on the new MC model which means I can't jailbreak it.
So instead I was gonna go to my friends house and exchange my iPhone 3gs for a 3g so I can jailbreak.
BUT I still want my contract to be goin so could I take the contract sim out of the 3gs and put it in the 3g??
If I put the the sim from my contract 3gs into the 3g will that mean that my mum will now be paying for the 3g and not the 3gs??

Cheers
hope u can help

Your contract will be continuing as usual. No matter which mobile phone are you using. Before swapping you SIM card, make sure that the iPhone 3GS and iPhone 3G are locked to same network or the iPhone 3G is free from network lock.
If it is locked to some other network, you need to unlock it in prior. You can unlock an iPhone using remote unlocking service. You can get the remote unlocking service for an iPhone from ClassicUnlocking.com You can also visit MobileUnlockGuide.com to get the free unlocking instructions for an iPhone.
