my buddy is swearing he's just getting a captivate, while this phone bears similar if not better specs, with the 4G speeds supposedly, of other things.

Does anyone else have comparisons to the predecessor Samsung devices to help me out before I decide on one of these? Are the network speeds comparable between this 4G and the HTC EVO 4G?

I guess lastly, do either of the 3 mentionned phones work on Wind Mobile in Canada? (AWS 1700 IV band)??
