What Phones Did iPhone Owners Have Prior?

"What phones are Apple's iPhone buyers throwing away? A lot of Motorola RAZRs. Some 29.4% of iPhone 3G buyers were upgrading from Motorola devices, according to Nielsen's Q2 2009 Mobile Insights Survey. About 11% of iPhone 3G buyers were ditching Samsung phones, and 9% were getting rid of RIM BlackBerry devices. About 9% were upgrading from older iPhones."

It stands to reazon that given the penetration of the Motorola Razr, a ton of people would be moving on from that and that's what the numbers seem to demonstrate.  Also interesting is the "other" category which, based on what isn't included, I would reckon is made up largely of Windows Mobile devices from HTC seeing as HTC is one of hte largest manufacturers of phones in the US and isn't listed on this graph.

Interesting stuff.
