What are the best phones to buy to test a new Android app?
<p>I want to buy a variety of Android phones to test an app I am writing right now. What would be the best phones to buy? I'm thinking it would probably be good to get phones with different screen sizes and even versions of the OS (I want to support versions 2.1+) but what other factors should I look for?</p>

<p>Thanks!</p>
