The BlackBerry 6710, which made its debut on Oct. 17, 2002, really made a splash. Where the 5810, released a few months prior, was the first BlackBerry to incorporate voice, the 6710 took that integration to another level.

The 6710 (pictured), a world band handheld operating on 900/1900 MHz networks in North America, Europe and Asia Pacific, hit the market with an integrated speaker/microphone and integrated wireless services like email, phone, Internet and two-way text messaging. It weighed 4.86 ounces and measured 4.73 inches by 3.03 inches by 0.71 inches.

The handheld featured a removable and rechargeable Lithium battery with about four hours of talk time, 10 days of standby time and three to four days of voice/data usage time. It offered 1 MB SRAM and 8 MB of flash, a plug-in SIM card, a backlit keyboard and screen and a headset with an answer/hang-up button. The 6710 also came with a cradle and travel charger for synchronization and recharging.

Another new feature, which made its debut with the 5810, was the BlackBerry Web Client, a Web-based application that let users access multiple existing email accounts, like ISP accounts, from a handheld. The client also gave users who didn't use Microsoft Exchange or Lotus Domino access to their personal email accounts, or folks who use those corporate email solutions access to both personal and corporate email.
