Shoring up its music-friendly line alongside the UpStage from Samsung, Sprint has announced its "Muziq," the Fusic's spiritual successor from LG. While it'll face some serious musicphone competition from across the CDMA / GSM divide later this week, the Muziq holds its own with some interesting features including an integrated FM transmitter that can send tuneage to any FM radio within ten feet. It also offers up stereo Bluetooth, a microSD slot supporting up to 4GB of expansion (a 64MB card is included in box), 1.3 megapixel camera, and sideloading of DRM-free music via USB. Look for it to hit on July 15 for $99 on contract.
