I'm not sure if this is the correct area, but here goes. In the past week or so when anyone calls my phone, the number comes up as "unknown". If the person is on my contacts list, their name comes up as unknown & if it's a regular number like my work or Dr office it also comes up as unknown. Even if I make a call, my call log shows the number I contact as unknown, even if I check my voicemail. It's driving me crazy since I always screen my calls. Has anyone had this issue befor? any idea what the deal is? I an on a G1 phone and my carrier is T-Moible.
