Got my iPhone some weeks ago.
It worked fine until some days ago, I upgraded it to 1.1.2 and continued with trying to ibstall anysim. Used some tips from ifon.no, it said to just follow the instructions and would take about 5 minutes. It seemed okey, but it never stoped..
After that, when I started the uPhone, only thing that happened was a black screen with the apple logo showing, and the "loading sircle".. This went on for 3-4min then it restarted black screen and the same; apple logo and loading..

Tried to fix it myself, now it is in activation mode. Tried to start the basic unlocking guide, but when I dial #307# it says "Call failed", same if I try 0..

Cant find anyone with the same problem..
Can someone help me with this?
Need my iPhone to work
