i have a jailbroken iphone 1.1.4 and have installed a good few applications on the phone already......

with all the new apps available but u must have 2.0 firmware or later to install them!!!!!

just a few questions:
1. will i still be able to use all my apps that i have on my iphone now (nes, snes, sega, neverball and many more)????
2. are there any other benefits of updating the firmware???

a while ago i accidently updated through itunes and locked my iphone and dont want anything like this to happen again!!!!!!!
