PC Mag checked out the Slider Sonic cell phone from Virgin, here's a short snip from their full review:

The all-prepaid carrier Virgin Mobile is popular with our readers, but it doesn't offer high-powered phones. At press time, Virgin sold ten different models, but none of its other phones offered removable memory or MP3 players (and none, including this one, had megapixel cameras). The Virgin Slider Sonic ($249.99 list), a variant of the Kyocera KX5, stands out among the carrier's selection but not in the larger world of high-end phones.
