The new devices include a range of GSM frequencies and 3G capability as well as WLAN and Bluetooth short-range radio technologies, Nokia said.

The E61 has a full keyboard and can send and receive e-mails while the user is making a phone call.
The E70 has a messaging keyboard, with a color screen for viewing e-mails as well as spreadsheets and presentations.
Nokia did not give prices for the new models.
