Bloomberg ran an article this morning discussing mobile phone trends. This article should be read by anyone who invests in Apple (NASDAQ: AAPL) because of the iPhone and anyone that considers Google's (NASDAQ: GOOG) moves in the mobile space to be a serious harbinger of what's to come for the mobile market.

As Apple rolled out its vaunted iPhone (it rocks, by the way) and Research in Motion (NASDAQ: RIMM) upgraded its phones to support video, Bloomberg reports that U.S. customers shelled out 40 percent more for handsets last quarter than a year earlier.

The article addresses a few salient trends in the mobile space:

• Analysts expect that North America will be the only region where the average phone price will increase this year.
  
• Last year, mobile handsets sold in Japan cost 74 percent more than in North America. In Europe, they were 10 percent pricier.
• Sales of pricier handsets such as the iPhone almost tripled last quarter and made up 11 percent of phones sold in the U.S.
• Shoppers spent $3.2 billion on phones, or $83 each, up from $2.2 billion a year earlier and the most since 2005
• The iPhone, which doubles as a music player, cost as much as $599 when it went on sale in June and now sells for $399. Apple shipped 1.4 million of them in the first three months. BlackBerrys go for as much as $300.

The Bloomberg article also describes the effect carrier-sponsored subsidies have had on the industry. "Carriers have used subsidies to keep prices of most other phones down. Motorola Inc.'s Razr, which sold for as much $500 when introduced in 2004, can now be had free," reported Bloomberg.

Carriers still act as "gatekeepers" in the industry. The carriers generally decide which devices to offer to their customers, and own the consumer relationship.

This all may change as carriers like Verizon (NYSE: VZ) have made announcements about opening up their networks to non-subscribers. Combine this with phone manufacturers continuing to produce better and more engaging devices and Google's attempts to create incentives and a platform for application development for the mobile device, and it's an opportunity for investors to pick some new horses.
