I know almost nothing about phones and some of those commercials that show a guy walking past the apple iphone line and having a clearly superior phone has got me thinking. I'm eligible for an upgrade and have an Iphone 3gs right now. I love it and would like a similar device with newer features. I know a lot of phones out there are "iphone killers" at a fraction of the price. What should i get? AT&T has a lot of smartphones in the free to $19 range with an upgrade. Here is whats interesting in my range and again I know nothing about them: htc hd7s htc inspire 4g impusle 4g lg thrill samsung captive samsung focus and focus flash and thats about it if I stick to the $19 and under range. Any insight would be helpful. thanx
