Which low end device?

You can send compiled .app files to people with the right provisioning profiles - I've done it myself in the past, but I can't remember the details beyond it being a huge palaver.

I'm considering getting an iDevice at the moment, and I think I'll go for a 4th gen iPod Touch. Hardware/software wise it seems to be pretty close to the 4th gen iPhone, just having half less memory. The 4th gen iPod Touch seems the perfect mid-end device, and when the 5th gen iDevices come out in a few months it will make a perfect low-end device. I don't think that supporting anything below 4th gen or 256 RAM is worth the hassle. To me the iPod Touch is also a good compromise between specs and price, since I don't need a phone and I'll be using it for testing purposes only.

You all have probably already checked these pages, I found them very useful and informative:

I'd get a 4th gen device so you can make use of the retina display.

If it's your first device go with a 4g touch, if you are worried that a game might not play on a lower model I would only buy another slower older device when the time comes.

If you build for armv7 only which is 3gs, 4g, iphone 4, 4s, ipad 1 and ipad 2 then the only lower model you have to worry about is the 3gs, and it's not that much slower then a 4g. It has a slower chip but it's not a retina device so less power is used up by the screen.
