The precedent has 161MB of internal data for storage. I recently hit the full mark of 161MB, and i have no clue how. Here are the apps i have Comes with phone, unable to move to SD: Facebook 14.36MB Maps 10.49MB Market 6.41MB Books 4.16MB Gmail 3.35MB Google search 1.27MB Street View 600KB 40.64MB in unmovable, unfree data Apps I've downloaded, and moved to the SD Messenger 5.76MB(amount that you can't move to the SD) Draw Free 3.92MB JuiveDefender 1.53MB Applanet Market 1.33MB Google translate 852KB PES2012 700KB Barcode Scanner 616KB App 2 SD Free 608KB SyncMyPix 492KB Prey 480KB(not moved to sd) Battery Solo Widget 180KB(not moved to sd) Advanced Task Killer Pro 164KB(not moved to sd) Juice Defender Ultimate 12.0KB 16.644MB of Used space in downloaded apps which would only total to 57.284MB in internal space taken by Apps. I've deleted cache on all apps, and deleted all sms threads, and still can't find whats taking up all my data. I'm running 2.2, and recently did the "pm SetInstallLocation 2" to supposedly set the default location of installs to be on the SD card, but when i try installing an App, it tells me that there's not enough storage room on my phone, and gives me a button to manage and uninstall apps. Although doing that allowed me to move some apps over to the SD card that i was unable to move before, such as Juice Defender. But i still can't find out what's taking up all my space, as not too long ago, i had even more apps installed, mainly large games, like words with friends, and angry birds, that took up space. After deleting the cache and messages, it dropped from 161MB used to about 158MB used. but then about 5 minutes later it was back at 161MB used, what could be causing this??
