Ah, iPAQ 610. You were so close, and yet... so far away. According to a handful of tipsters, after a round of delays, HP has decided to cancel the release of its upcoming Windows Mobile smartphone, the 610 (also known as the iPAQ 614, 614c and 600). The company didn't give a lot of information, though they did state that, "due to recent legal issues between suppliers of mobile phone technologies, HP has decided not to offer the iPAQ 610 Business Navigator to U.S. customers as previously planned." It's unclear whether this means the phone will be missing from shelves worldwide, but it certainly won't be popping up on these shores anytime soon.
