This is a very simple app, all it does is remount the select mount point as RW or RO.
I wrote this because some apps have problems remounting partitions as RW and thus do not work as a result. By Remounting the appropriate mount point an app that did not work, can suddenly begin to work.
Anyways, very simple. There is a Donate version on the market if you would like to donate for this work. This version and the donate version are the exact same for now.
In Remount 1.1
