For some data subscribers, Sprint's TeleNav-sourced navigation service
just got a little more accessible. The Power Vision "Ultimate Pack" and "Business Pack" bundled data packages now include unlimited nav use -- great for folks prone to getting hopelessly lost on a regular basis -- instead of paying for it a la carte
. An entirely new package, Power Vision "Navigation Pack," also includes unlimited use plus the usual suspects (unlimited on-device data, mobile email, and so on, but don't even think
about tethering) for $20 / month. Not worried about losing your bearings daily? Subscribers to any other Sprint data pack can now get their nav on for $2.99 per 24-hour period, too.
