Is it possible to force 3G on Iphone without jailbreaking?
<p>I've heard mixed results regarding forcing the iPhone to 3G operation only (so that it doesn't switch between 3G and Edge)..  this is supposed to improve call consistency (read: fewer dropped calls - which i seem to have a lot of problems with).</p>

<ol>
<li>does anyone know how to do this without jailbreaking?</li>
<li>otherwise, any tips on getting better reception/reducing dropped calls?</li>
</ol>
