Hi What your describing sounds like your trying to remove the primary gmail.com account.
If there is more then one can you remove the other one? I do not believe it is possible to "swap" the accounts creating a new primary. This limitation, either by design or accident has been a thorn in my side, I want to give my wife my old phone and she likes the way its set up and running but I cant because it wont let her "swap" the gmail
I tried that already and it did not work. Yes there are 2 gmail accounts. I am doing this for a friend and according to her she did not create that second account. It's really strange. Thanks to all who replied so far.
