Hello all. I am with Rogers wireless and I'm from Canada. Rogers is basically the same as Cingular and I live alongside the Canada/US border. Initially my caller id was working when i bought the phone. I am running 1.1.2 and the phone is unlocked. Now when a call comes in all it says in UNKNOWN. Moments after a missed call I get a auto-text, which i always get after a missed call and in this text it states the number that did call. Ive tried a new simcard with no avail. When I put another persons sim card in my phone and call their number the caller id does work on my phone. Getting frustrated please any recommendations welcome.
