thanks for pointing that out. just posted a new one at 0 bytes, not sure we can get much smaller than that.

When i try replacing these mp3's it just keeps saying access denied.

I'm sorry, but this instruction makes no sense to me.

I have an older ver of Kilmist RegEdit installed, but I don't see from your directions what that has to do with using the FileExplorere.  What am I missing?

Do you cut/copy/paste the app? How do you move it?  When I tried moving the Windows cache, all I got was an indexing error.

Meanwhile I cannot use the camera because it's complaining about not enough memory.  BTW, is there a way to get the Messaging app to store email in My Storage rather than main memory?  That's one of MS WM's dumbest ideas.

yanktar... you dont have to read through all 25 pages of posts to make sense out of the original instructions. you just have to read the original instructions properly.  

you cannot move/copy/paste files with a RegEdit program.  the program to use - Total Commander - is a RegEdit and file exploring program.  the stock windows mobile file explorer does not allow you permission to overwrite system files, where as a third party program, such as Total Commander, does.

if i could offer you some advice though... i wouldnt waste your time worrying about the memory saving steps.  if your device is anything like mine was... packed full of programs, and low on memory, the only way to save it is to flash to a custom ROM.  you cannot save enough memory by following these steps alone.
