Trying to find my current firmware version

[jdmz33]

Hello, I have a 2G 1.1.1 iphone and had some problems before where it kept on freezing. So I gave it to my friend to try making it ok but he screwed up and I don't know which firmware version I'm in.
Right now I can open the phone but it is stuck at the Emergency dial screen and does nto recognize my SIM.

When I click the little "i" on the right bottom of the slide for emergency screen, it shows:

IMEI: 01 130000 554533 1
ICCID: 8988 6920 0140 2374 2400

Can anyone tell me what version of Firmware I'm using now?

Thanks.

Nope, no Idea. But you can put in DFU mode, restore in iTunes, set up as new phone and jailbreak it again. Very easy to do, you'll be fine.

i would just restore and rejailbreak to save yourself time from looking for solution
