I tried the tool also.
After setting the option to install to SD I installed the IMDB tool and PicSay.
Both gave the error 'Application was not installed'. When I switched it to internal memory, they installed just fine.
However I don't see the option to move a program. I'm looking in Settings>Application settings>Manage applications and then selecting a tool. The 'Move to SD card' is not available, not for the old tools I installed as for the both tools I did after installing this setinstalllocation tool.
Any bright ideas?
The SD card is formatted with several partitions to make it all run so I don't know why it won't work.
