I see a lot of posts about jailbreaking 4.1.

What is the easiest way to upgrade from 4.0.2 on a 3GS to 4.1 if you are already jail broken? Does it require me to do a restore and have to load all my JB apps and regular apps again?

Does 4.1 have that many benefits over 4.0.2 on a 3GS that its worth my effort?

What is the easiest way to do it?

Thanks!
