Who is going to jailbreak today?......
not me...im already jailbroken. i tried running my phone un-jb for 2 weeks and didnt like it. felt too restricted and working around my phone took longer than when it was jb.
i use mywi, bitesms, lockinfo, sbsettings, activator, and folderehancer. all of these lets me quickly get things done.
bitesms - i can send text anywhere on my screen, reply to text without exiting an app.
sbsettings - toggle any control on/off front my status bar (bluetooth, wifi, vibrate, adjust brightness) instead of closing out my apps to get to settings.app then browse around trying to locate that one toggle.
activator - activates whatever i need with gestures in any apps
folderenhancer - i can keep my springboard nice and tidy. able to put more than 12 apps in each folder, i can put folders in folders.
lockinfo - display all my upcoming events on my lockscreen instead of opening up my cal.app.
mywi - obviously for tethering. i DJ and a photographer. so when im at a gig - people request for songs and if i dont have it, i can log into my DJ source to grab the song needed. i can transfer files wirelessly during a photoshoot.
this is how i use my jb apps. others may find use of them differently, but it helps me get things done quickly.
like others have mentioned, jbing is not for everyone. for people that complain about decrease stability, battery drain and security, you're probably installing things without researching. it is impossible to brick your phone. i dont use SSH - i use iphonebrowser/iphone explorer so security is not a problem for me at all.
