For much of its life Virgin Mobile USA has been the exclusive domain of Kyocera and UTStarcom cell phones. Yet that began to change last year when LG offered the new LG Aloha LX140. And now just a couple of weeks after LG added its second Virgin Mobile phone, the LG Flare LX175, it appears Samsung is joining the carrier's family. On its Web site, Virgin Mobile is promising that the Samsung Slash is coming soon. The slider phone sports a slick design and a functional feature set that includes Bluetooth, voice dialing, a speakerphone, messaging, a camera, MP3 ringtones, and a wireless Wen browser. We don't know pricing or exact availability, but we'll keep you posted.
