Is Android development restrictive in any way like for the iPhone?
<p>Is <a href="http://en.wikipedia.org/wiki/Android%5F%28operating%5Fsystem%29" rel="nofollow">Android</a> development restrictive in any way like the <a href="http://en.wikipedia.org/wiki/IPhone" rel="nofollow">iPhone</a>, or can you download whatever and from whoever you want?</p>

<p>I want to learn about development for either iPhone or Android, but from what I hear iPhone development is pretty restrictive!</p>
