I have over 8GB free on my SD card. Yet when I try to move a downloaded app such as Image2Wallpaper (approx. 9MB) to the SD card I get a message saying there isn't enough storage space. Any idea what I'm doing wrong? (PS...Under Application Manager, I see a number of apps that are supposed to be on the SD card yet drilling down none appear to actually be using an SD card. When I look at storage under settings, I see I have 11+GB of USB storage and about 8Gb of that free, but under SD storage it says "mount" SD card and "insert SD card." Do I actually have SD storage? If not, can the Galaxy SII 4G have an SD card added?
