Cingular Wireless may have been somewhat late to the push-to-talk (PTT) party, but since it joined the fun last December, America's largest carrier hasn't been shy about introducing new PTT models. The first two handsets, the Samsung SGH-D357 and the LG F7200, did not offer cameras, but the third model in the series, the LG CG300, came with a VGA shooter in a nod toward shutterbugs. And now to broaden its PTT selection even further, Cingular offers the Samsung SGH-D407. Packed into a simple but appealing design, the SGH-D407 offers a decent feature set that includes the aforementioned PTT support, a speakerphone, Bluetooth, and world phone coverage.
