I bricked my iphone, got an unlocked 1.1.2 replacement i think:)!!!!
Amazing news i used the 1.1.2 OTB unlock which was the method by using an application on the iphone and run it and it unlocked it, however it bricked my phone and wouldnt switch off and just stayed on apple logo screen.
I sent it off for repair, got a new replacement iphone and it seems to be unlocked, it is running my o2 PAYG sim card, its on 1.1.2 firmware 04.02.13_G modem firmware. Gunna try and make phone calls soon on it, then gunna try and update to 1.1.4 firmware via itunes and see if it still works, im really excited:)! Could make alot of £££ from a legit unlocked iphone.
