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.
Not much of an update here, changed the wordage around.
Let me know if you have feature requests!
