Question

i only have a ipod touch and is it enough for me to test an app i have write for an iphone?

Answer 1

It's best to have both an iPhone and an iPod Touch for testing purpose. However, don't worry if you only own an iPod Touch. As long as you don't use iPhone-only functionalities (phone, SMS, etc), you're good. One bonus is that the iPod Touch is generally less powerful than an iPhone, therefore you know how well your app performs in a slow device.

As for the location-based service, iPod Touch uses WiFi to determine locations, so if you don't need GPS, you're good to go.
