Hi All, I'm an iPhone 3G user. My battery is starting to go caput, though, and more and more apps won't run until I install IOS 5. Am thinking of buying a 4S. From the buyer's guide is looks like it'll be another good 100 to 150 days or so before a new model comes out (the average is skewed by more frequent early updates -- the cycles keep getting longer in fact). What would you do if you were me? I'm not the type to update every time a new iPhone comes out. The 4G is interesting, not sure what other features would make a different to me. Thank you!
