Important Trouble Shooting. Update 06-08-2010
Fix the "THE SIM CARD INSERTED IN THIS IPHONE DOES NOT APPEAR TO BE SUPPORTED" problem
itunes have made some changes to block unlocking of iphones on 06th august 2010, and will lockdown the iphone to use only original sim even if jailbroken and unlocked via jailbreakme and ultrasn0w.
If you dont have one already get an activation sim from iPhone Activation Sim Card
remember, the activation sim is only to activate and get you past the "slide for emergency" and give "slide to unlock"
we have uploaded a full guide to our servers, you will find it at http://www.fonefunshop.co.uk/simhelp.zip
this help file will show you how to activate it, jailbreak and unlock, it pays special attention to the problem created by itunes update today that is blocking access to the phone even when unlocked.
