I use a Contour HD 1080p fixed focus Helmet Cam to record, one period of three hockey game periods at a time. The time to record a 20 minute playing time period is something like 25 to 30 minutes with a file size for each period of just under 4GB. Will the iPhone 4S record 1080p video for a complete 60 to 90 minute hockey game? I have not seen anything in the specs or discussion of this for either the iPad2 or the iPhone 4S. Any thoughts about this?
