iPhoneDownloadBlog points to an upcoming jailbreak-only tweak, which promises turn-by-turn voice navigation for the native iPhone Google Maps application. The tweak is said to be “coming soon” to Cydia with no specific launch of pricing information being available at this time. Turn-by-turn voice navigation in iPhone Google Maps has long been a popular feature request, and hopefully Apple brings it natively in future iOS upgrades. (via RazorianFly)
