Competition: it’s what the free marketplace thrives on and usually results in a big win for the consumer. Sprint and Palm appear to be more than willing to take up the mantle of David and sling some well-aimed stones at the Goliath of AT&T and the iPhone.

In an ad posted on Sprint’s Facebook page, Sprint pulls no punches in pointing out a few advantages with joining their carrier and taking home a Palm Pre: 1) running multiple apps at the same time, 2) real-time updates, 3) save $1200 over two years with their aggressive calling/data plans, and 4) the first 4G network in the wings. Note also the timeliness of this advertising – going after the original iPhone customers now that their 2-year contract is up.

Keep swinging, Sprint and Palm. After all, you won’t land every punch, but you only land a punch if you are swinging away.
