What are you guys doing different with your phones now that you jailbroke them?
I only tried once and something went awry so I had to restore my whole phone. Haven't tried since.
the top reasons I jailbreakSBSettings (The A#1 reason to jailbreak above all others, will finally get implemented in IOS6 in some fashion though)
Also
MailEnhancer+ if you have several email accounts it really helps organize things 100% better
LockInfo >>>>>>>>>>>> The IOS5 Notification system. IOS5 tried to copy lockinfo and didn't quite get it right. I don't know why they just didn't buy the company
Activator - Change all the activation settings. IOS5 implemented some of these features, but was really half assed.
Action Menu - Help text swipes. This I think would even be more money for Ipad
TetherMe - Enough said
Springtomize - Sort of an all in one tweak manager.
3GUnrestrictor - Enough said
5icondock - obvious
Some new ones I haven't tried
DashboardX - Makes your phone more like Android with widgets. This also looks very likely implement on IOS6. Long time coming.
Stride - Android unlock style
If you are still on IOS4
BiteSMS - This actually has some advantages for IOS5, but not worth the money anymore on IOS5 IMO
there are also a ####load of Siri tweaks. I think Siri is a poorly formed POS, but maybe someone has made something of it in Cydia. I hear AssistantExtentions is good, but I haven't tried it.
There are also a ton of tweaks to change things like the color of the bubbles, clear the bubbles, change what shows up on top line all that crap.
