Gave me an iPhone 3gs, which, according to indirect data, have been made update the firmware. Apparently to 4.2
Background of the iPhone is not known to me, but it looks like I bought it in Russia. Can be and the United States.
Now the screen is emblazoned the logo "connect me to itunesu" and displayed the IMEI and ICCID.
When connecting to itunesu requires that you insert the original SIM card.
What can be done and in what sequence?
I even have AT&T mikroshemka there, but it is mikroshemka.
PS I do not know how to find out modem version and all the rest.
