3G fix for Thunderbolt

I was wondering why i still had 3G when no one else did. I used this fix long time ago, and never changed it back.
 
Ok everyone seems to be reporting that LTE is back online, if you are in a 4G area it is advisable to make sure you switch to eHRPD to avoid bad hand offs between 4G and 3G as well as allowing simultaneous voice without hiccups.
