currently using ipad4, JB on 7.0.6
lately i find it to be quite slow, animations abit sluggish, and not as smooth.

worth to update to 7.1.1? got smoother and faster?
if i update i loose JB feature, i actually only use one feature, which is able to use iTools to transfer movie/videos to VLC folder directly. fast and easy, way faster than wifi transfer.

if after 7.1.1 update can become faster and smoother, then i dont mind loosing JB

are you sure? i use iTools, but without JB cannot write to any system folder.
which include app folder too, since they are in system directory

Wow your using I tools from 2011 version?

I tried using latest itools to copy movies to vlc player app folder for non jb IPad. And I conform it doesn't allow copying files into it.
