Samsung gave us a nice surprise today at CTIA, when it showed us the sleek, high-end Ultra Edition phones that it first unveiled at last month. In addition to the U700, U600 and U100, Samsung also highlighted the F700 QWERTY phone. It was under glass and devoid of any handy signs detailing its features, but the slider phone is obviously meant for messaging addicts.
