Google Nexus 4 for Android Development?
<p>I want to buy a phone for android development and testing. I know that Galaxy Nexus has good reputation among developers what about new nexus 4?
<BR><BR>In Nexus 4 my minimum OS version will be 4.1.2 or 4.2. If I wanted to test previous versions would I need another phone? 
<BR><BR>If I upgraded nexus 4 to next OS verson (for example android 5.0) I would be able to downgrade it to 4.1. How complicated is to flash ROM on Nexus series? </p>
