Hi! I'm a relative Android newbee, had MyTouch 4g for two months. I'm having problems with the "Low on space" warning. I have moved all my apps to the SD card which helped for a while but the warning came back. I then started clearing out data, uninstalling apps but days later it still came back. I read about the "diskusage" app and have it installed after clearing more data. What it is telling me is of my total data (1162 MiB) 115 MiB is free, 63.3 MiB is Applications and 983 MiB is "System data". There is no way for me to tell what this system data is made up of. I installed diskusage on my wife's MyTouch 4G and found her system data was only a little over 100 MiB. How can I clean up the system data so I get my phone back to normal? Thanks!
