I've been experiencing a lot of "Low on space" error messages on my Desire recently. The amount of free space seems to fluctuate in the range of 10MB to 20MB (sometimes changes on a reboot, etc.) I've gradually been deleting apps over the last few weeks whenever it goes below 15MB (this is when it starts to be "Low on space" and lots of things such as Gmail, Talk, etc. stop working). When I look at my list of applications, I have an application called com.htc.socialnetwork.provider which uses 40MB of data - by far the biggest there. I've been on Google and struggled to find information about what it actually does and why it might be using that much information. It sounded like something to do with Facebook sync so I turned that off and disconnected my FB account from Sense... it dropped to about 39.5MB. I was wondering whether anyone knew what com.htc.socialnetwork.provider might do, why it might be using so much data and whether it would be safe to "Clear data" on it? As it's an internal HTC Sense application, I don't really want to delete a vital database or something. Thanks a lot!
