Linksys today finally publicly announced its WIP310 Wireless-G IP iPhone. The 802.11b/g SIP phone first showed up in the FCC ID database in late 2006, but was only previewed with select customers during last year.

The "candy bar" style phone has a 1.8" backlit color LCD screen and is spec'd at 3 hours of talk time and 50 hours standby. It supports WEP and WPA PSK wireless security and WiFi Protected Setup.

The phone is primarily aimed at service providers and will not be available until 3Q2008 at a suggested list of $200.
