Nokia 6800 series

These phones were marketed as "messaging devices": all had built-in email clients, and some had BlackBerry support.

The 6800 and 6810 had four electrical contacts at the very top of the phone for the left side of the keyboard and another four just under the screen for when the regular 12-key numeric keypad was being used.

A small magnet was built into the left side of the keyboard and the phones would switch to landscape mode as soon as this was lifted up.

This was essentially the business version of the 6800 devices, with significantly upgraded connectivity options, build and screen.

By the time it was released, the 3.5MB of memory it had was considered insufficient[3] and the phone was not on the market for long.
