My phone was brought on the 2nd of january 2008 in london, o2 sim.

I thought that it would be easy to jailbreak it and wait for the 1.1.2 otb unlock, using it as iPod.

My problem is that every time I'm in 1.1.1 my phone cannot connect with wi-fi, so cannot jailbreak with or .

So I decided to go to 1.0.2 and my wi-fi come back.

Later I decided to HW unlock with testpoint, My phone is now with bootloader 3.9 and modem firmware 04.02.13_G and with phone firmware 1.0.2 jailbreaked and unlocked.

Do you know any way for me to upgrade to the latest firmware 1.1.3 or 1.1.2 that does not need to pass thru 1.1.1 ?

Another thing that might be important, when I downgrade from 1.1.1 to 1.0.2 with iTunes 7.5, my wi-fi can connect only with ip ranges of
But if I downgrade with iTunes 7.3.2, my wi-fi connects to any network.

Please try to help!
