l had a similar problem. I installed a utility called disk usage from Play. This showed (using the App storage opttion) that I had just under 1 gig of Applications, 800MB or so of "system data" and about 200MB of free space.
Reading threads in other forums indicated that this was probably due to something called 'alog' files. It seems that they are protected and the only way to delete them directly is to root your phone.
I didn't want to do that, so I did a factory reset (I'd been intending to do so for a while as I had been getting random crashes and I thought a rebuild might help). Anyway, after the reset the system data & tree space had radically changed. I now have 900MB of free space and 100MB of system data.
I have no idea if the 9900 code described above would have done the trick, but it sounds likely.
