Sprint has added its new location-based services to some of its high-end plans, reports RCR News. As well as adding the services to its $25 Power Vision Ultimate Pack and Business Pack, Sprint has launched a $20 per month Navigation Pack which includes the location based services as well as unlimited web browsing and data access, MMS, e-mail and other multimedia services. Other Sprint subscribers can buy the service for $3 for a 24-hour period. The new location based services are from TeleNav and include voice-guided, turn-by-turn driving directions, moving 3-D maps, local search, traffic alerts and a feature that locates the least expensive gas nearby. TeleNav also runs the new workforce-management offering launched by Cingular earlier this week, which offers GPS location-tracking, mileage-tracking, wireless time sheets, alerts and detailed location-reporting.
