Data released today from comScore shows the largest purchaser of iPhones since the G3’s launch in June 2008 are those with household incomes of $25,000 to $49,999. Coming in second is the $50,000 to $75,000 income group.

Since the release of the first iPhone in January 2007, 43% of all existing iPhone owners earn over $100,000 annually. comScore suggests that the middle income markets are the most active iPhone buyers, right now, because the unit is small and covers multiple functions, eliminating the need to also purchase other devises, hence a savings.

Perhaps the middle market comScore describes are iPhone patrons, earlier in their careers and in their 20s or 30s, catching on more quickly to new technology, favoring a small unit that encompasses more functions, eliminating the need for toting multiple other devises.

For commuters, in particular, less rather than more to tote across town to work is attractive. For long commutes, entertainment is a plus.

Still, Blackberry does continue to be savored for its professional image and lower price tag among business and finance professionals, linking Office email, calendar and contact functions to the phone. It is a good buy.

Like the Blackberry or its equivalant, iPhone also links desktop functions and offers greater flexibility to those using Apple compatible products. iPhone does provide greater options for entertainment through iTunes, games and music. It is first-rate for either office or recreation.
