Don't have US$300 to shell out for the new Motorola SLVR iTunes Phone 2.0 that I mentioned yesterday? Then make your own.
Tea Vui Huang's Mass Storage Synchronizer is an iTunes add-on that allows owners of some Sony Ericsson, Nokia, Samsung and PalmOne Treo phones and PDAs to use iTunes to manage their songs, and sync the songs to the phone - just like the Motorola ROKR and SLVR.
Devices that work with Mass Storage Synchronizer include: the Sony Ericsson Walkman Phones (w800, w600 and w550) where it replaces the bundled Disc2Phone, Sony Ericsson P900/P910 Smartphone, Sony Clie PDA, Samsung (SGH-E350, Z500, D600, E530C, E720C, D500),the PalmOne Treo and some modern Nokia phones.
The only drawback is that the applications is currently Windows-based so Mac-heads will be forced to find a PC or use VPC to use it.
Back in September the PowerPage's Emory Lundberg posted a story about SyncTunes a Freeware application for Mac OS X which lets you push items from iTunes to a removable storage card, such as an MMC, Memory Stick Duo Pro or SD - making it simple to manage content on your device. SyncTunes transfers files to Palm PDAs, Sony PSP, Sony Ericsson K750/P910/W800i, Siemens SX1 (Symbian s60), and generic MP3 players.
