<p>I've already read <a href="https://outdoors.stackexchange.com/questions/5446/what-specific-features-should-i-take-into-account-when-buying-gps-device-for-geo">this</a> and <a href="https://outdoors.stackexchange.com/questions/4045/how-to-select-a-good-gps-receiver">this</a> to get some background knowledge on GPS tools, but I'm still left with some questions:</p>

<ol>
<li><p>Is there any way I can get a device that consistently provides accuracy to within 10 feet in less than a minute or two?  </p></li>
<li><p>I've messed around with several iPhone apps, but haven't had very good luck thus far.  What's the most accurate a phone can be?</p></li>
<li><p>If I can't have accuracy to less than 10 feet within two minutes, what's the closest I can get to that goal? (Both in terms of time and accuracy)</p></li>
</ol>

<p>I only need to be able to accurately determine the coordinates of specific locations, so I don't need any additional features--even poor battery life isn't a big deal.</p>
