Ipod Touch 3G vs Iphone for app development.

Answer 1

Ipod touch is missing some features of the iphone.

• You don't have the phone,
• You only have wifi network (no 3G network)
• No Camera
• No GPS
• and some other matters (like accelerometer and compass)

You can start with ipod touch, and unless your app is using any of the above then you should be ok. But make sure you plan your app and see if it will require any features that might not be on the ipod touch

we are using ipod touch but also testing on iphone (mostly for no-wifi scenarios)
