The K630 also provides a true music experience. It comes with 256MB Memory Stick Micro (M2) in-box and supports up to 4 gigabytes – that’s up to 3600 full-length tracks. That sounds like a lot, but the K630’s Mobile Broadband (HSDPA) capability means it only takes about 14 seconds to download a full-length music track*; up to four times faster than average on a regular 3G phone. To make things easier still, the K630 features a dedicated music key to help you navigate all of those songs.
