Dashwire: it’s fabulous
Dashwire is beautiful. It’s basically a way of backing up the entire contents of your mobile phone, the contents of which are stored centrally by Dashwire as opposed to on your hard drive. It syncs automatically using your data plan (via a client-side app. on the phone), and even allows you to send SMS messages or call people "from your phone" directly from your PC via the stunningly beautiful web interface. No PC-based client-side app. necessary.
