If you bought your iPhone thinking that it was going to be a great new tool in your small business arsenal you might be disappointed by this news: only a mere 3% of the applications available in Apple's App Store are actually targeted at business. That's a surprise, given that back in March, Apple CEO Steve Jobs announced that the iPhone was getting a software upgrade that would make it more appealing to business.

Here's the good news, though: the number of business apps is growing, reports today's Wall Street Journal. Just a month ago, there were only 23 business apps. Today there are 65.

As far as the popularity of business apps go, Salesforce, sales software, has been far and away the App store's best seller. That's not terribly shocking consider that a lot of the apps aimed at business still seem relatively useless for the average entrepreneur or business owner. Read: they suck. For instance, how many people would actually find the Drapery Calculator—aimed at soft furnishings and drapery manufacturers—helpful? Or what about GarageBuy, an app that lets you search and bid on items on various eBay sites. Er, unless you trade on eBay for a living, what's that got to do with running a small business? And, for some reason, half the business apps inexplicably seem to confer the ability to make and send voice recordings. On the other hand, other Apps like the Remote Desktop seems like they would have real, practical applications.

All you iPhone business users out there, what do you think? Have you found the iPhone particularly helpful for business? And are there apps that have made your life as an entrepreneur, business owner, or wannabe any easier?
