I've run into a problem - I keep using up too much space on my iPhone from my camera roll-particularly with the iPhone 4S now shooting 8mp stills and 1080p video. What is a good app for storing my camera roll in the cloud? It would be great if I could locally store low-resolution compressed stills on my iPhone and then if I need higher resolution simply download the full resolution copy. They key here is I want it to be as quick to use as the camera roll app on the iPhone. Any suggestions would be greatly appreciated. My webhosting service gives me essentially unlimited storage space so if I can take advantage of that instead of paying for a service it would be great.
