No you may not. Apple's apps cannot be used for any phone other than the iPhone. If you want a cheap way to use all of the apps for the iPhone, get an Apple iPod Touch. It is $199 and it has no monthly bill, whereas the iPhone is $99 and it has a minimum $75 monthly bill.
Yea at least on my iPod most apps don't use data indent know if it's different for an iPhone though
Although iPads can download apps made only for iPhone/iPod Touch, the iPhone can only download iPhone or iPhone/iPad apps. Apps made only for the iPad do not appear on the App Store. Luckily most of these apps have an iPhone counterpart such as Angry Birds (iPhone) and Angry Birds HD (iPad only).
The first generation iPhone can have any of the new apps. But the GPS enabled apps won't work as well because the 1st generation iPhone uses cell phone tower triangulation to get its position which is not as accurate as the GPS chip in the iPhone 3G. Other than that the software is the same.
The good news is that IPhone tracking is available and the ... you can look out for such as the GPS tracking ... iPhone Jailbreak News - iPhone Apps - iPhone ...
Well, the iPhone 3g has a camera so any apps that have to do with that won't work. Other than that no.
yes, but not all iphone 4 apps are available on the iphone 3gs/3g/2g becuase they are too high resolution apps, or need a front facing camera.
No, one of the main reasons is that the ipod touch/iphone apps are not made for any other type of ipod. Without a touchscreen or an accelerometer it would be impossible to use any of the apps.
