title: iPod touch for iPhone development
body: <p>I am thinking about buying an iPod touch to make some money on developing apps for the iPhone. I like the concept of the App Store and had a quick look at it with iTunes.
  Looks like applications are categorized, to be iPhone OR iPod applications.
  Some apps which are free for the iPod seem to cost for iPhone users.</p>
  
  <p>What is the difference of both platforms, or why is the App Store separating them ?
  Does it make sense to develop for the iPhone using an iPod touch (beside phone/location related apps) ?</p>
  
  <p>On developer.apple.com I can sign up for selling my Applications on the AppStore for 99$.
  Do I have to expect any further costs ?
  Is it a problem to develop from outside the US (in my case Germany) ?</p>
