I have an 'old' iPhone (non-3G) and I installed the 2.0 software. Then I found out there wasn't a simlock available for the 2.0 just yet, so I wanted to downgrade back to 1.1.4, but it wouldn't let me. All iTunes says is (something like): the sim card in this iphone does not seem to be supported, blah blah blah. so anyone know how to downgrade it anyway? mind you, i can't access the main iphone screen in itunes with 'restore' and 'update' in there. PS: live in belgium. bought the iphone in the US, so i had to unlock it.
