Since you can't replace the iPhone battery I was thinking of another solution. It would be nice to see a case maker come up with some sort of case/charger that would fit around the phone. Basically, a case the phone gets inserted into that has an integrated battery. Obviously, this would increase the bulk and size of the phone but might be handy for those times you need extra juice. I know Belkin makes a charger that attaches to the bottom of the phone and gives you another 3 hours of talk time or so. Again, not the perfect solution but better than going with no power at all.
