I actually did get a pre-paid LG smartphone TracFone(android) from HSN a couple years ago, and it's more fun with a much better camera and virtual keyboard for texting. It does drain the battery much faster due to all those little Google apps running around though. I've only seen one problem with it so far, in that it turns off wi-fi sometimes for no reason. But, I don't use that phone much either.. Don't like to be tethered/addicted to my phone like many of the younger folks I see!
My thought on Android smartphones is that "settings" is your new best friend!
Haven't got a clue on iphones tho..
