How to determine whether user is on Edge or 3G on iPhone
<p>Though it is relatively straightforward to determine if an iPhone is on Wifi or a data network programmatically in your application, I can't figure out a way to determine if the iPhone is on Edge or 3G. </p>

<p>Anybody figure out a way to determine this?</p>

<p>Note: Not worried about Apple AppStore acceptance policies so I don't mind doing something hacky in my app. (The iPhones should not have to be jailbroken though)</p>
