I have read the instruction for unlocking on the following link http://www.iclarified.com/entry/index.php?enid=2538

and I have a question for step 6, which is : do we need to have our iphone connected to the internet for doing this step ? Since at the moment my 3g iphone is under lock status, and cannot use the simcard in my area. (btw, my location is in Indonesia)

Cheers
