How much free space does everyone like to keep on their phones? See below for my current allotment. Luckily, I can fit my entire music library. But I get nervous whenever I start taking a lot of photos or video. I know 7GB is PLENTY (considering my last iPhone was 8GB total), but I still feel a bit cramped. If I add much more music I may have to compress everything down to 128K. What about you guys? How much free space do you like to keep?
