With three cell phone companies and multiple cell phone models available, no two cell phones go head to head more often than these two. The iPhone (by Apple) and the BlackBerry (by Research in Motion) are hands-down the two most popular phones sold today. So, how do you know which one is right for you? See how each one ranks in the following categories to help you decide:

Applications – If having lots of software options on your phone is important to you, then the iPhone is your clear choice. The iPhone has over 1,000 application options available and easily trumps the BlackBerry’s very small list of programs that only include a word processor, a spreadsheet, and a PDF application. Granted, many of the iPhone applications are frivolous, like the “How Old Are You In Neanderthal Years?” calculator, or the daily horoscope update; but some are actually useful for business purposes, such as the available project management, time tracking, or financial calculator software. Both the BlackBerry and the iPhone have software that allows you to use them as mini computers; but if you want to be able to convert your phone into a remote for your stereo, only the iPhone can do that.

Durability – From all the research we’ve done online, the BlackBerry wins in this category. The BlackBerry was actually created with business users in mind and therefore is a sturdier phone. If you have traveling sales people or remote users who need to stay connected to the office, the BlackBerry is less likely to get damaged than the iPhone. Although the iPhone has made definite strides in this area, dropping that phone on its face assures that you’ll have to get a new one.

Business Functionality – In the not too distant past, the iPhone didn’t have the business functionality of the BlackBerry. However, iPhones now integrate with Microsoft Exchange, which is one of the most common e-mail applications for small and mid-sized businesses. Both the BlackBerry and the iPhone have the ability to synchronize your contacts, calendar, and e-mail. Apple is also making attempts to ramp up the security of their iPhone; and as it stands today, the BlackBerry is the most secure of the two phones.
