Testing for bugs on Apple devices that you do not own

I'm starting to send out a beta version of my app for users to test. One came back and told me that the app crashes on her iPod Touch (2nd Gen). How do I debug for this considering I don't own one. All I have is the iPhone 4, yet there 9 other devices (each gene开发者_运维知识库ration of iPhone, iPod Touch and iPad) that I would like my app to run on. Any advice?

EDIT 1

There is no iPod Touch hardware option in the simulator. Should I just assume that it is treated as an iPhone?

Hoptoad App is great for this. You can sign up for free for up to 1 project, and the implementation is very easy.

For starters get the crash logs from your users' devices and try to debug based on those. Not a big help in testing on devices you don't have, I know, but at least you'll be able to figure out what crashed on each device your beta testers have...

You could try Apple's IOS simulator.

To set the iOS release used in the simulation environment, choose Hardware > Version, and choose the version you want to test on.
