The sync seems to be working fine as it is synced. However I'm not getting notifications anymore upon receiving an email and also when ever I open the gmail app it no longer refreshes itself I have to do it manually every time. Could this have something to do with moving the app to my SD card or maybe the fact that I deleted Google talk because I don't use it (that doesn't seem logical to me though, unless somehow the notifications are dependant upon something in Google talk)
