Nope, remember when updating/restoring, that it has to re-activate before it starts working again..

[mernst]

is there anyway round that????

I can also confirm this. I tried to update to 1.12 yesterday sans sim card.

???? so it doesnt work.... ?????

Nope. You must have the valid SIM in the iPhone.

Well what would happen if you had 2 iPhones? One is active and one not active without the sim card. Could you take the active sim and put it in the non-active and update, then switch the sim back to the active??

Needed to be re-activated. Inserted my SIM and off I went.

off-hand, I would say no, but obviously if you have an unlocked phone on
T- Mobile and you can sync, I would expect that you should be able to swap around SIM cards.
But the reason I say no is because an iPhone SIM will work in Any GSM phone, Not any SIM can work in the iPhone - even if it's an AT&T SIM. So I would suspect that the SIMs are IEMI encoded when registered, and that keeps the chip from activating other iPhones.

I just went today to inactive it and restore my phone to factory.... JUST WHAT... I can still use the phone.... so eh
