First question:

I have installed a lot of apps and I wonder if I move application directory to user partition and make dynamic link and upgrade to 1.1.1 will I be able to run my applications by making the same dynamic link after upgrading?

second question:

I decided to upgrade to 1.1.1 before but since upgrade didn't go well downgrade to 1.0.2 but kept base band in 04.01.13_G and after unlocking with anysim it works perfect without any problem. Do I really need to upgrade to 1.1.1?
