iOS 5.1 Disable 3G Return

*** UPDATE ***

AT&T pulled this feature from the final 5.1 release.  It was present in the 5.1b3 release.  It is present on other carriers.  Guessing AT&T had it pulled becuase they decided to show 3G as a 4G icon and this option would have been even more confusing.

For iPhone users who are live or travel in a non-3G area (only EDGE / 2G), a battery killing feature is having your iPhone constantly scanning and looking for 3G signal.  Before 5.0, there was the option to Enable 3G or Disable 3G, but starting with iOS 5.0, Apple removed that feature. Well, Disabling 3G has returned to iOS 5.1 and for those in non-3G areas, you can now gain a ton of battery life.

Also, for those that find themselves at an event with a huge number of other people (sporting events, conventions, etc) and have had difficulties sending a text/email/photo, disable 3G and you may find that you drop to the slower network that nobody else is using and your stuff will get through faster.
