Has anyone talked to apple about this as it seems to be there issue and not ATT's. Anyone conect customer support or the forums? I purchased a MC last night and got it up and going with my 4s. Worked until this morning when I turned the 4s On and notice it was at my default 3G cell site which was low signal and not the MC. So it makes sense and backs up information about the phone picking a lower signal tower then the MC with a higher signal. We need to get apple involved.
