Over the last few days, my Gmail has stopped syncing several times intermittently, with even a manual refresh having no effect. Coincidentally or otherwise, downloads from the Market have been taking absolutley ages to start over roughly the same period. Not sure whether this is connected, but these symptoms started at about the same time that I started getting "Low on space" warnings on status bar - though I still have about 13MB spare - surely enough to sync a few emails and complete small market downloads? Rebooting the phone seems to get Gmail working again, and kicks pending downloads from the market into life as well. Which would seem to indicate that memory is not the issue. Has anyone else noticed these problems? P.S. This is a stock Desire, with the recent OTA firmware update. Hmm, am now also wondering whether this may be linked to that OTA update...?
