Will iCloud allow a user to not keep as many apps, songs, videos, etc. on their phone? Can you access these files from the cloud or is the cloud just for backup and cross syncing use? Can I store an app on the cloud say NBA Jams and play it through the cloud? I'm asking b/c I'm trying to figure out what size HDD to get on the 4S, 16 or 32 for me. Any insight or advice would be appreciated. I'm on a 16GB G3S now and have used up all but a gig on stuff and that's with holding back/un-syncing things.
