I was trying to install a new application and i was always getting an "out of space" error. "Application name" could not be viewed. Free up some space on your device and try again. I had enough free space on the /nand, the /sdcard, /system, /data... But my WiFi was closed. I turned it on, and finally i was able ton install the application. It seems that the free space was refering to the wifi. I hope this will help somebody else.
