Sony Ericsson has announced two new Cyber-shot phones this week. The quad band, 3G, 5.0 mega-pixel power house K850i (US compatible) and its little brother the tri-band 3.2 mega-pixel K770 (missing the 850 MHz frequency) are the latest high end multimedia phones to be offered by Sony Ericsson. Both phones are packed with features typically reserved for PDA style phones. 

With 3G speeds users will be able to take advantage of the video calling feature found on both models along with video blogging, push email, full HTML web browsing and other streaming media (carrier dependant).

The K770 and K850i are scheduled to be released in the fall and Q4 of 07 respectively. Although no pricing information has been released, I would expect to pay between $400 and $500 for the K850i making it an interesting toss up for those considering the iPhone.
