It'll be interesting to watch/monitor the working life expectancy of the battery over the course of 3G iPhone ownership. With all its chockablock features --- voice, video, iPod, email, aGPS, WiFi, etc --- a heavy user could really work a battery into the ground...
A few of many possible scenarios:
.... work a battery into the ground,
a: before the 1 year warranty expires
b: just after the 1 year warranty expires (gotta luv planned obsolescence

c: before a 2-year contract expires, thereby precluding a user from the customary new contract incentive, like an iPhone upgrade
d: and for our fellow Canadians, before a **3-year contract** expires (the lone option for an iPhone)
Having an easy(ier) battery access might be beneficial all 'round.
