You need to get your E200 App. Unlocked, then edit the registry (YOU MAY NEED TO MAKE A SETUP CAB FILE TO DO THIS!! Due to permissions)
HKLM\System (Create a key(folder) called FileSys)
HKLM\System\FileSys (Create a STRING called TempPath)
Set the Value to TempPath to: \Storage\Application Data\Volatile
You can download this attached cab file which does it all for you! It will also give you cleartype (sorry if you dont like cleartype but i had to edit this setup.xml to get my reg settings in, i dont understand the setup.xml language to take the cleartype stuff out).
Sorry im not making sense as this is a complicated procedure!
Feel free to post if you get confused/stuck
Took me all day to do this, Microsoft should employ me.. jks
