I'm not going to split hairs on this subject and get into a debate on non-JB vs JB....alot of people assume that we jailbreak to find "free" apps/games....totally not true...but here are the links to the demo vids for the apps I previously mentioned.
But I jailbreak to:
Have multiple signature's for emails ~
Create/password protect photo albums within the native photo app ~
To be able to have live move-able widgets for the lock screen ~
Sorry...I only wanted to insert links to the vids instead of embedding them...no other way...that I could find.
The above PAID apps have been developed to look and feel as if they should be in iOS by default.
I'm sure apple monitors forums and the JB community for potential idea's for future updates.
So if you're watching Mr. Jobs......take note!
