Gphone: How to change Gtalk and Gmail accounts

Recently, I am playing with the company's gphone, but the Gmail and Gtalk accounts cannot be changed. After searching for half a day, I did not find the answer (some people think that I can only restore the factory settings, Dizzy ~). After exploration, I finally found the method.

In the ApplicationProgram/Manage the application, clear the data of two checkin services (one is Gtalk, the other is Gmail), and then restart (do not know if it is necessary, not as detailed as the test ), done!

Clue: a login error is always prompted during the previous startup. It is estimated that the check in fails, so I tried to clear the data of the checkin service. Haha, as expected!
