i've looked around, maybe not so much on here but ive spent loads of time in google and still don't have much of an answer to my question. where can i find, or what, are the differences between firmwares on 5g ipods other than "bug fixes"? i still have version 1.2.1, and have no problem with it. i never updated for a few various reasons. BUT i have seen some of the newer smaller ipods with the split screen cover flow feature and want to try it out. i have alot of mixtapes or albums and sometimes forget the names but recognize the album covers from itunes coverflow, it would help me out to preview an album cover when looking for something. i heard theres a search feature to that may or may not be useful to me. is my understanding of those firmware options accurate? is that ONLY for the new ones or would i find it on my ipod if i updated to the most current firmware?
