It’s one of the more interesting gadgets you will see this holiday season – the T-Mobile Cameo – a picture frame with its own cellular modem so it can receive photos directly from mobile phones.

Cameo’s technology was developed by Parrot a few years ago.  T-Mobile is selling it to U.S. customers for $100 and a $10 monthly fee.  The device already received a positive review from the Associated Press.

The picture “frame” – a 720 x 480-pixel LCD – gives owners the option of accepting or declining the photos it receives, along with the option to always accept photos from specific senders.  The frame can mount in landscape or portrait modes, can play slide shows, and has a microSD card slot and USB slot.

Wireless LCDs that act as pictures frames aren’t new, but most only have a Wi-Fi connection.  T-Mobile says its Cameo is the first U.S. frame with a cellular connection – a unique way for a carrier to increase its subscribership without actually adding new human subscribers.

Industry analysts say such products will become increasingly popular in 2009 because of decreasing margins and subscriber saturation in the mobile voice market.
