I noticed today I cannot send any email from my phone. The emails just get stuck saying "Sending..." Has anyone had this problem before? Thanks in advance! Found the fix: (forgot about step 2 which was causing some confusion) Go to menu -> Settings -> Applications -> Manage Applications. Then click menu -> Filter -> All. Scroll down until you see the Gmail and Gmail Storage. Click both of these and select clear data. The phone will then resync with Gmail and all should be well.
