I used my Iphone for 1day (in sweden) it all worked fine, I could see the carrier name, make calls etc.

The batteries died during the night, when I started it I had only one bar of reception but I couldn't see the carrier name and I can't call ("Call Failed")...
I put in my brothers simcard, he get's full reception and can se the carrier name etc. But we can't call either, ("Call Failed")...

I use bricktool to fix if it has gone in brick mode... No change...
I restore it with itunes, use ziphone... no change...
I restore it with itunes, use iLiberty+... no change...

I still got 1 bar of reception but no name of carrier...

Does any one know what's wrong?
