hello, just quickly, i have a 1.1.1 jailbroken ipod touch. if i update to 2.0 will it erase all my music videos and pictures? or as in a previous post will it back it all up first and put it back? also, i have heard people with Ipod touchs having problems with 7.7 if they dont have an up to date FW, im curious if anyone has any idea if i will have a problem downloading 7.7 itunes updating to 2.0 and then keeping all my music and videos. thankyou much!
