My wife uses an 8700 but I want to give her either my 8100 or 8800 when the 8300 is finally available on Cingular (I have a Cingular SIM) - but sounds like that's not going to work.
Any help in confirming would be helpful and thanks in advance.
You could also just take the simm into a cingular store and tell them you are having problems with it, and they will just give you a replacement. Just tell them the device says invalid simm once in a while and you think it is going bad. When I had the Moto Razr I had that problem with a cingular simm I just took the simm into a store and they gave me another one.
