So this weekend my Zune reached the point of 3.75 MB of free space remaining. With my iPod 5.5G sidelined for a few years because of harddrive lag, and my Zune now out of space, I realized that I need to upgrade. However I don't want to do a regular 'New iPod purchase' but something more fun. Upgrade iPod Video 30 80GB to 120GB HDD mk1224gah - eBay (item 250691849228 end time Apr-01-11 09:20:55 PDT) My first plan was to just buy that, switch out the harddrive and have a fresh new 120gb on my old iPod and stop there. But then I started thinking. If I'm gonna upgrade the harddrive, couldn't I just upgrade everything else? Basically what I'm trying to do here is turn my iPod into a 6G iPod with a 5G body. Having hacked and modded my iPod numerous times before, I know this isn't simply just a firmware overwrite - the innards of the current 5.5G are not compatible with the firmware of the 6G iPods. So I'm thinking of buying the hardware from 6G iPods to replace on my 5.5G iPod so it will be 6G firmware compatible. Am I crazy or could this just might work? Can anyone help me out? What hardware I need to swap out, how to get my Computer and iTunes to read it as a 6G iPod, etc? Did some research, looks like I may or may not have to switch out for more RAM for this to work, but definitely need a new processor? Before I make purchases I would like to know is this even possible?
