Correct Answer: LG KE850

Now let's learn something…

Announced in December 2006 and shipped in May 2007, LG's KE850/Prada was the first mobile phone to be sold with a capacitive touchscreen, arriving a month before the iPhone. In fact, an LG executive at the time accused Apple of copying the Prada when it was unveiled and won a product design award in 2006.

LG's phone had a 3-inch 240x400-pixel display, supported microSD cards up to 2GB, had a 2MP camera with LED flash, and support for FM radio, while the follow-up LG Prada II (KF900) arrived in December 2008 with a full slide-out QWERTY keyboard and a front-facing camera.

By the way, the BlackBerry Storm 2 didn't have a capacitive touchscreen, but was instead the first and remains the only smartphone to have a full clickable touchscreen powered by piezoelectric sensors under the display.
