No real carrier but carrier name still present
my friend has one of the first iPhones 2G, bought from AT&T and since then being used unlocked in Poland.
It always worked ok, but now we have no idea how to fix a carrier problem. The iPhone shows carrier and in the begining works ok, but after couple hours no calls are possible and no sms is being recived.
And the iPhone still shows carrier name.
At first we noticed that problem while upgrading to 2.2.1. But then, after couple days we somehow fixed it - probably because virtual operator which has country roaming in other operator started to build his native stations.
Since couple of days we have the same problem after ugrading to 3.0. We tried everything we can think about and nothing helped.
PS. Maybe my friends operator or sim card is broken?? His iPhone seemed to work ok when he was living abroad for a while.
3g with no ring from incomming calls
My 3g was doing the same thing - no ring, no sound and the display would stay lit. I restored several times but this did not fix anything so this last time I did not install liveclock, weather icon or sbsettings and all is fine now.
