My wife and I both have HTC Incredibles purchased at the same time and we now both have Low on space but, when we look at our storage capacity we have plenty everywhere. We deleted some apps we never used any way. But, this did not fix this issue. It is annoying and does keep us from doing certain things on our phones like FB etc. what is up with this mess. Also my Gmail will not sync and give me any mail new or old. About ready to go out and buy new phones!
Hello Greenweenie, Let's give you back control over your phones! It is possible the internal cache of apps like Gmail and Facebook could be filling up. Try Menu>Settings>Applications>Manage applications>All>Choose Gmail or Facebook>Clear cache and/or data. Please keep me updated on the status as I would be happy to offer additional support.
