Help Change google account failed

[shigekiwong]

Hi all,

I have a Magic that upgraded to the HERO Sense UI (download from offical site)

I have cleared the data of Google Apps, Gmail, Gmail Storage, Google Search from Setting->Applications->Manage Applications
Also, killed the process - Market

I have tried to sign in to google account again, it shows message:

Can't establish a reliable data connection to the server.
This could be a temporary problem or your SIM card may not be provisioned for data services. If it continues, call Customer Care.

I can go to Internet by browser.
Any one know what is happened? How to solve this issue?

Thank you very much!!
