Interface

• Many Blackberry devices have a full QWERTY keyboard for typing emails and text messages, as well as a trackball for navigation. The iPhone does not require a physical keyboard or input device, as the interface is navigated exclusively through a touch screen. Depending on which application is active, the iPhone allows the user to interact by providing on screen input and controls.
  
  

Wi-Fi

• Apple's iPhone includes Wi-Fi support ,which allows users to access the Internet at wireless hot-spots. This is especially useful when the mobile network is unavailable or lagging. The Blackberry 8830 does not offer Wi-Fi support, but does offer EV-DO (3G) support, which is absent from the iPhone.
  
  

Display

• At 3.5 inches diagonal, the iPhone's display is significantly larger than the 8830, which is a full inch smaller. The iPhone also boasts a superior resolution of 480X320 pixels, as opposed the the 8830's 320X240 resolution. Both units are capable of displaying more than 65,000 colors and offer video playback.
  
  

Camera

• Apple's iPhone comes with a 2 megapixel camera, which is decent considering that it is part of a multimedia device. The Blackberry however, does not include a camera at all. This seems to indicate that the device was geared toward professionals, as opposed to the average consumer, which is Apple's target market.
  
  

Battery Life

• Apple claims that the iPhone's battery will last for 10.4 days of standby time, and 8 hours of talk time. By comparison, RIM's Blackberry 8830 is rated for 3.6 hours of talk time and nine days of standby time. While the Blackberry's battery is not as long-lasting as the iPhone's, one major advantage to the 8830 is that the battery is user replaceable whereas the iPhone's is not.

• Originally retailing for $399.99 in the United States, the original iPhone was significantly more expensive than the $199.99 Blackberry 8830. The original iPhone has since been discontinued, but the follow-up model is available from AT&T for $99.99. The Blackberry 8830 retails for $49.99 from Verizon Wireless as of September 2009.
