The new version 2.1 fried my SIM card, I have to go for a replacement so that I can use my iphone 3G.
The SIM card is useless and it does not work on any phone, also I have noticed that the ICCID is blank.
I think that Apple has released a new firmware that can burn the sim cars if you use a hacked iphone.
My iphone 3G is not jailbroken or anything and it is from Telcel/Mexico.
I bet that the new firmware is more difficult to hack and can destroy the SIM cards.
