I've tried for 2 months to do it my self but I NEED HELP updating unlocked 1.0.0

Hey guys...

For anyone that could possible spare a moment of their time to I guess explain it in dummy terms how to upgrade an unlocked iphone (1.0.0) to the newest 1.1.2 with every step I should take.

I've tried for a while now search up on the net on how to do this my self since i first got the phone and the first upgrade came out, but I guess I've been to scared to do anything to screw up my phone and guess I'm not as computer savy as I though...

Also I'm using FIDO (Canadian Network) on my iphone atm... I used my phone in London, Greece and Rogers (another Canadian network) and the phone and voicemail all worked out fine on the phone telling me with the red bubble that i have voicemail... FIDO doesn't... :s anything fixable?

Thanks in advance

James

hmm... i'm really not savy with this at all...

1.) where do i get 1.1.1
2.) How do i "jailbreak revirginize" from that site?
3.) after revirginizing the phone will it erase everything?
4.) i didn't see anywhere in your instructions where i actually do the upgrading bit?

so i followed your instructions and it's now a brick! how do i fix it...? i can't even restore it.. it wont finish the process...
