Calling smart developers: Stop Bing 4 auto upgrade!! There is a legion of Bing mobile users who have been left in the dust with the latest forced upgrade of version 4 to version 5. Version 5 has cut out a lot of very nice and critical features like real-time GPS turn by turn direction tracking, true full screen map view, more intuitive interface (in my opinion) to name a few. After much research, it appears that non-Verizon subscribers get to retain many of the good features, but Verizon forces you to by the VZ Navigator if you expect to use turn by turn GPS navigation ($10/mo). So that only leave out a few million users! Are there any slick developers out there that can either prevent v4 of Bing from doing a version check or have v5 retain the navigation for Verizon phones?
