Turn-by-Turn voice guided Navigation and Outdoor Navigation for Windows Phone 7

Some of you may already be familiar with the super nice Outdoor Navigation application for Windows Phone 7 developed by GPSTuner but what you may not know is that the same developers have also recently released a Voice-Guided Turn-by-Turn navigation application for Windows Phone 7. To put it simply: Both applications are just awesome and are some of the best mobile apps I have used.
