Hi All 
This is my first post here.
My device is a Samsung S Duos running ICS, rooted but with stock rom and no mods etc.
I had used links2sd and moved most apps including libraries and app data to 2nd partition of a 4 gb sd card which was an ext3 partition.
I recently gave that phone to my wife with an 8 gb card.
When I tried to reinstall some of the common apps back I got "Insufficient space" error.
I realised that this was because remnants of the old installations were still on the internal memory so the ones that I found I uninstalled and was able to reinstall most of the apps after doing that.
However some apps like facebook, twitter, youtube and maps etc I am still unable to install either because I am unable to find their relevant file remnants to remove (fb, tw) or because there is no uninstall option as in the case of youtube and maps.
Can you please guide me what to do further.
Thanks.
