The 6210 was the 10th BlackBerry released by RIM but the first with an integrated phone. The 5810 had been the first to have phone functionality, but it required a headset to work. The 850, introduced in 1999, was just a two-way pager. Released in 2003, the 6210 offered e-mail, phone, SMS, a Web browser and BlackBerry Messenger, making it the modern BlackBerry we've all grown to love. Or hate.
