I really enjoyed using the Samsung Instinct, sold by Sprint. Sprint has great multimedia and GPS applications intergrated within it, making it fun using a phone like this. It's well designed, making it easy to understand, and I had no big issues using the touch screen -- the touch-screen keyboard is easy to use because it is horizontal.
The software is music-player friendly, with quick access links to download songs from Sprint. If you want to use your own mp3s, just throw them on a microSD card.
Even though there's much to like about the Instinct, it's not perfect. Read my 60-Second Review or watch the video below:
