I'm currently using an iPhone 4 (32 GB) and it's always full. I keep a ton of applications on it (that I never use) and video podcasts, etc. I'm thinking about upgrading to the iPhone 4S (64 GB) but I'm now unsure because of iCloud. If I understand correctly, iCloud actually downloads the content to the iPhone so it's still taking up space, right? Doesn't that basically defeat the purpose of "streaming from the cloud" ? Also, does iCloud work for videos?
