insufficient space on device I am getting "Insufficinet Space" errors when I try to update whatsapp on my HTC desire. I am running CyanogenMod 7.

My filesystem usage looks like this:

What I would like to know is exactly what partition I need to free up this missing space on. /system and /data all seem to have 25M +, and I am trying to update Whatsapp. The current Whatsapp app is just a little over 10M so should fit as far as I can see from this.

I appreciate that similar questions have been asked on this site before but I have tried various solutions mentioned there already such as removing unused apps and re-mounting the cache partition to the sd card.
I solved a similar problem.

If nothing helps, you should show us a log from DDMS.
