I’ve received several emails from people who were told in AT&T stores today that Microsoft is working on a “fix” for the microSD expansion reliability issues. As a result, AT&T is now telling its employees not to install microSD cards in Samsung Focus phones until that fix is available, and it is advising customers not to upgrade the phones themselves.
I have asked Microsoft to confirm or deny this.
You may recall that Microsoft told me this upgrade was problematic, while AT&T previously said it was not. If this is true, AT&T has finally come around. Stay tuned.
