Got to admit, much as I am loving my Desire, Android simply IS NOT READY for the average Joe. My son has a T-Mobile pulse and for the second time, his Gmail, contacts and calendar stopped syncing. No reason, just stopped. Search and found "solution" of clearing some data in the Application settings. Re-started Gmail and it's prompts to set up the Google account. Enter correct details and after a couple of minutes get the "Can't establish a reliable data connection error". Even though it's on WiFi and can browse, Facebook, etc. Have searched and searched and tried all the suggestions. Tried doing it without WiFi, without sim card and everything. Only solution that worked last time (and the only one that seems to work for everyone) is the factory reset option. So my son now loses all his sms messages, saved games/high scores, settings, etc and has to go through the whole rigmarole of re-installing everything and setting it all up. It shouldn't be this way.
