All well and good but I do hope and wish Apple would do something to dramatically improve iPhone battery life and or make the battery easily removable as in other cellphones. If Blackberry can do it why not Apple.
Keep your iPhone powered up for long trips: “up to 24 hours of talk time, 72 hours of audio playback, up to 21 hours of video playback, and up to 30 days of standby time”
