4g is irrelevant right now as you won't find it where you live. Going with iPhone means that you get the best user experience because it is controlled by apple.
Its very cool. For apps, nothing beats the app store for iPhone. It dwarfs what is available for the droid phones.
You're correct on 4G right at this moment but I assume this person is going to keep his phone for more than 1 month when 4G comes to Des Moines. You're probably right though, if you live in Lamoni 4g probably doesn't matter.
"Android stocks 134,342 free applications alone for download, while Apple’s App Store has 121,845 free apps". Both have over 200K apps. I think that's enough. So far my friends with Iphones have showed me 2 apps that I wish were available for my Android. I showed them a lot more that are not available to them.
