NPD says 30% of iPhone 3G buyers switched carriers, Google Street View and more said to be in 2.2 firmware

The NPD Group offered a bit of insight into the carrier-jumping habits of original iPhone buyers way back when and, as you might expect, it's now back at it and taking a stab at determining exactly where the iPhone 3G's users are coming from. According to the group, between July and August of this year, 30 percent of iPhone 3G buyers ditched their existing carrier to buy the phone, which is a somewhat significant uptick from the 23 percent of consumers overall that switched carriers during the same time period. Of that 30 percent, 34 percent of 'em switched from Verizon, 24 percent came from T-Mobile, and 19 percent came from Sprint. That same report also pegs the BlackBerry Curve, BlackBerry Pearl, and the Palm Centro as the next best selling smartphones. In related news, the 2.2 firmware beta floating about has apparently turned up a few more hidden surprises -- namely, support for Japanese emoji icons, an off setting for the auto-correction feature and, purportedly, support for Google Street View in the Google Maps application, although there's unfortunately no screenshot evidence of the latter feature just yet.
