Its the same Apple app store for all devices, yes.
Yes. They both have the same screen sizes and can both use the same apps.
You download the app and then sync the itouch or iphone to your computer. Warning: You can not download apps on anything but an itouch or iphone.
iPhone came first, then the iTouch.
No, that would defeat the purpose of the "iPhone" which is the iTouch with the cell phone. The iTouch is the iPhone without the phone. If you want an itouch with a cell phone, get an iPhone.
Yes but you have to jailbreak it first or wait for the SDK
yes you use the same device
they are two different things! an itouch is basically everything that the iphone is without the phone. you can also install most of the apps that you can on an iphone on an itouch
iPhone and iPod touch games (or other apps) are never compatible with an iPod nano.
No, on the Iphone you can call people. On the Itouch you cannot call people, but you can text people's phones.If you have a Itouch 2nd generation you can download skype buy headphones with speakers on them and call them that way.but whatsoever you can not take pictures
the itouch is cheaper because the iphone you have to pay for a bunch of things that cost alot
An iPhone is an iPod Touch (iTouch) with the phone and camera. Thus, an iPhone is already an iPod touch with more features.
Yes. The iPhone was released in January 2007, the iTouch was released in September 2007.
