Samsung just got busy with a trio of MP3, AAC, AAC+, e-AAC+, WMA, and WMDRM supporting musicphones: the dual-sliding SGH-i450, slim SGH-F330 with HSDPA, and SGH-F210 swivel stick. Most impressive is the €360/$508 Symbian i450 with Touch Wheel music navigation pictured above. Slide ‘er up and you’re holding an S60 3rd Edition smartphone with 3.6Mbps HSDPA data beneath a 2.4-inch LCD. Slide ‘er down to expose metallic speakers with a B&O ICEpower amplifier and Samsung music UI for controlling the tunes stored in its 35MB of internal memory or up to 4GB on microSD expansion. Sure, Bluetooth A2DP stereo audio, 3.5-mm headphone jack, and FM radio as well. The €260/$367 F330 features the physical music controls of the F300 while packing 3.6Mbp HSDPA, a 2 megapixel camera, and up to 2GB of microSD expansion in a slider measuring just 13.5-mm thin. The F210 then, is a GSM version of the U470 already nabbed by Verizon as the Juke. It offers up to 20-hours of audio playback from the included 1GB storage or microSD expansion — we hear it makes phone calls too. Sorry US Americans, all these phones are tri-band GSM and set to launch around Europe starting this month.
