I take back all the bad things I said about SwipeSelection. The newest updates work somewhat well with the sliding shortcuts and KB Shortcuts. The difference between SwipeSelection and SwipeShiftCaret is that SSelection swipes on the keyboard while SSCaret swipes in the text area. The problem with SSCaret is that it can be hard to utilize in text fields embedded in scrollable areas (like say when trying to make a post in a webpage that's been zoomed in a bit). SSelection is better that SSCaret once SSelection it's been made compatible with other keyboard tweaks and shortcuts.
appslide has been updated for iOS6. Pair with SwipeNav** and Zephyr for a smooth UI experience without tapping buttons. Love the flow, almost as good as webOS imo and better than Android.

not to mention all the swap message history, swap photoroll, save snapchats, lock folder/apps
Can enable some down low behavior. Don't trust anyone with a jailbroken iPhone haha.
**SwipeNav doesn't work nicely with one or two apps. The Transit App was crashing on startup and I narrowed down (using the sbsettings substrate addon disbalble) the cause to be SwipeNav. That was the only app though and after disabling SwipeNav for that app in Settings, it worked properly thereafter.
