Rumour today has theSamsung i677, a Windows Phone Mango smartphone, which probably has a full keyboard. Pictures of this new smartphone are not yet available, but there are some clues.
Earlier phones in Samsungs i6 series ran on Windows, and had some kind of a full keyboard. This is an indication that this is a device with a full keyboard and Windows Phone, but speculation based on the model numbers offer no security, off course. What seems sure is that this is a Windows Phone handset. A profile sheet that surfaced recently gives evidence top believe this.
Until now, the Dell Venue Windows Phone Pro is the only device with a full keyboard. This keyboard slides under the phone in portrait mode. It is possible that the i677 uses the implementation, as the strict rules that Microsoft has for creators of Windows Phone devices also leave room for a different form factor, with the keyboard on the front below the screen, like a BlackBerry.
