I am planning on getting an 8gb iPod Touch and am going to jailbreak it. I have about 5.5gb of songs, and probably wouldn't use it much for movies. I would like to fit all my songs on there though. I read somewhere that the 8gb has close to 7.2gb out of the box. How big is the jailbreak? I would probably consider getting a 16gb if I can't fit all my songs on the 8gb after the jailbreak. It would probably give me some room to have a few shows on there too. So how much room would I have left with 5.5gb of music after the jailbreak with the 8gb? Would it be better to pay the extra $100 and opt for the 16gb?
