Thunderbolt by dialing down those crazy LTE speeds from time to time? Then you now have a relatively easy way to do so courtesy of the new LTE OnOff app that's just hit the Android Market. That's apparently similar to a few other options available, but this one's free, and it will let you switch from LTE to 3G only with just three taps. Sound good? Hit up the link below to download it straight to your Thunderbolt.
