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!!
