I have recently upgraded to 2.1 on my pulse and everything worked ok for a day or two. However, yesterday and today my phone just seems to have just stopped syncing to gmail. I turn on the 3g, background data, and auto-sync buttons, as well as wifi when available, but nothing happens. I've turned it on and off, took the battery out, cleared cache etc, but nada. When it's syncing it usually shows a little white circle going round and round, but the symbol just stays green, with no rotation, and nothing happens when I click refresh either. There's no indication that there's a problem, no message, nothing at all. I haven't been able to use the market either as apps keep stalling on download or nothing happens either - I don't know if they are related? Is there a way to start a force-sync or do something to prompt it to start syncing again? Or should I reinstall the OS again? This is all a bit frustrating!
