I'd use the Infuse 4G to lord it over my iPhone friends stuck on 3G connections! Har Har!!
I adore QWERTY phones, and I would use the Samsung Stratosphere to find my dream girl on OKCupid! (That'll involve a LOT of typing! :)
I would use this phone to get Sprint TV and cancel my cable service! Hello, savings!!!
Heck yeah! Sign me up!
