Samsung’s impending F490 and P720 touchscreen phones have been spotted outside of official press events with new details to match, says Russian site Mobile-Notes. The F490 (shown) is now known to include haptic feedback, vibrating the phone when a user touches a control on its 3.2-inch display; though slim, it has a 5-megapixel camera and (currently Europe-only) HSDPA 3G access. Its interface is better than that of the LG Viewty it will challenge on launch, the Russian report says.

The P720 is similar to what has been expected with a 3.2-megapixel camera and a smaller 2.6-inch screen; the device now carries the Duos name to reflect its dual SIM card slots that allow frequent use of two different services without losing phone numbers or suffering roaming charges. Neither phone has had an official release date set, though speculation places announcements of one or both at this year’s Mobile World Congress in February
