Sidekick lookalike could be 4th edition

What you see here is a Sharp cellphone that was paraded at the recently concluded IFA 2007 in Berlin. It looks as though it shares some genetic material with the famous Sidekick line, and chances are pretty high that this could be the Sidekick 4 that everyone has been hankering after. What do you think – is this a legit version of the Sidekick 4, or is it just some marketing tactic by those folks at Sharp to throw everyone off the trail? The buttons don’t look to great to type with though.
