Here's my situation:
I bought a 1st Gen iPhone from US about 1.5years ago, I had it "flashed" and unlocked/jailbroken to 1.1.4 firmware. After this was done I was urged not to run software updates when asked by itunes when plugged in. My idiot brother tried to run an update to 2.2 last night resulting in an error msg that reads some thing like "sim card is not supported, please try new sim card or original sim card that came with iphone". The phone itself is not functioning, it displays a 'USB cable' with an arrow to 'itunes' icon and thats it. I'm assuming its now locked again.
Does anyone know how to fix this?
How can I unlock/jailbreak again on my own?
Any input would be much appreciated.
