There's no shortage of enterprise implementations for the iPhone as a third wave of iPhone-focused solutions begin to emerge into the business markets.

News latest comes from Lab49, which today announced it has begun developing applications for the device for the financial services industries, focused on buyers and sellers within those markets.

The company confirmed it has seen "sizable and growing demand" for developing financial applications on the iPhone, and notes that hedge funds seem to be adopting Apple technology fastest of all within the sector.

If, like me, you aren't in these industries, then what kinds of implementations are being discussed? Simple: applications include: real-time information and data visualization; mobile workflow management; and monitoring and management of real-time trading applications and high-performance infrastructures.

First fruit of the new development wave is "Lab49 Capital", an iPhone application that shows real-time portfolio management on the device. It's nice because it helps portfolio managers track the performance of their assets in real time, and "slice and dice" positions, P&L and changes in the portfolio across multiple dimensions such as strategy, industry, country and manager.

"The new iPhone platform presents significant opportunities to buy-side and sell-side firms," said Marc Jacobs, director at Lab49. "The extension of financial applications to workforces across multiple floors, buildings, geographies, and client sites; faster response times to complex financial, legal and technical events; and quicker time to market, all make for a new wave of applications that can actually be applied throughout the financial enterprise."

We've come a long way from Gordon Gekko's phone haven't we?
