Since I'm currently on a 4s that is not Jailbroken, I've decided to compile a list of apps/tweaks that I miss the most. These are all "must have" apps for me, and I plan on adding them immediately when a JB for the 4s comes out.
In no particular order:
BiteSMS: I really miss the ability to text and reply without unlocking my phone or leaving the current app.
ManualCorrectPro: This app basically let me edit the dictionary. I would could add commonly used words to the dictionary, this made texting/typing much easier. No longer an option.
SBSettings: I often adjusted the brightness given the lighting around me, or toggled the 3G, E, and wifi depending on battery life.
RunningList: Showed a list of all running apps in my spotlight. It was nice to see what apps were running, what I needed to close, what I left open, etc.
SpeedIntensifier: Just made the phone run faster.
