various government agencies to start looking into ways to proactively prevent it, rather than just pass laws against it, but Sprint is being more proactive than most. It's announced an app called Drive First, developed by Location Labs, which won't be available until sometime in the third quarter. The app runs on Android and basically puts your phone into lock-down mode "when driving is detected," automatically sending incoming calls to voicemail, auto-replying to texts that you're unavailable, and preventing you from using much of any applications outside mainstream navigation fare. As always with these apps we're not sure just how they'll differentiate between driving and, say, sitting on a train, and we're guessing they'll be just as effective at locking out those riding shotgun, but for parents worrying about whether Junior is texting when he should be driving home from band practice it could be a good solution. That solution, however, will cost those 'rents $2 per month -- and certainly won't earn them any love from their angsty teen.
