has anyone been having problems with their Sony Ericsson t68i the past week? I can rarely get a signal in areas where i would normally be fine and other phones seem to be workin ok.
The transmitter(s) you are using may be down for maintance (i had this problem for two weeks on Orange last year).
Have you contacted your operator. The T68i seams to need a stronger signal than some other phones to work okay, which may explain why others appear to be okay.
