I've been on my 1.1.1 8gb touch for a while now. i would like to upgrade to a jailbroken 1.1.4 without losing all of my apps and music. is this possible? can i just copy everything on my 1.1.1 ipod to a temporary folder via ssh then upgrade to 1.1.4 through itunes then jailbreak? are there any disadvantages of using 1.1.4 over 1.1.1?
