Do you recoomend any best mobile out of all mobile phones with gps?

Recently while I was checking out for latest offers in cell phones from T-mobile I came across, BlackBerry Curve 3G - Graphite Gray, which is available for $49 with T-mobile. This slim and stylish BlackBerry provides the advantages of high-speed 3G Web browsing, Wi-Fi connectivity for voice and data, access to BlackBerry App World, built-in GPS and visual voicemail to keep you connected on the go. The only thing you need to make sure before working with these facilities is to get a web service plan on your T-mobile as it is required. Other than this if the qwerty keypad doesn’t hold much importance, you can chose for Samsung Vibrant, a Galaxy S Phone, which is a sleek Android -powered Smartphone with a stunning 4” Super AMOLED screen and 1 GHz processor that makes everything you experience more beautiful, it has everything in it and is the best suited choice for you but the only thing it misses is the QWERTY keypad in it, but the super fine touch screen quality will never let you to regret for it. And the cost of the phone is $149 which is extremely close to your budget.
