Probably one of the most iconic and easily recognizable BlackBerrys to hit the market was the BlackBerry 6210. Announced on March 17, 2003, the 6210 brought a smaller form-factor to the once brick-like -- or as some have called them "pancake style" -- BlackBerrys that came before it. Distinguishable by its bold blue casing, the 6210 can still be spotted in the wild every so often.

The 6210 (pictured) was billed as offering "a smaller design with a light and comfortable feel, increased memory for greater application and data storage, as well as new support for wireless email synchronization and integrated attachment viewing."

Taking cues from some of its predecessors, the Java-based 6210 delivered email, phone, SMS, browser and organizer applications on one handheld device. It also supported international roaming with World band 900/1900 MHz GSM/GPRS operation.

The "sleek" device measured in a 4.45 inches by 2.91 inches by 0.83 inches and weighed 4.8 ounces. It featured an embedded wireless modem, an internal high performance antenna, a thumb-typing keyboard and navigation trackwheel. The 6210 had 16 MB flash memory plus 2 MB SRAM, a rechargeable/removable lithium battery, USB connectivity, a large screen, integrated speaker and microphone and an intuitive interface. IT also featured a backlit screen and keyboard for anytime reading and typing.

Like the BlackBerrys before it incorporated mobile push email, phone, SMS, browser, organizer, application integration, BES support and BlackBerry Web Client.
