Another first for me is using Bluetooth. For the last 24 hours, I've been putting wallpapers, MP3s, and .3gp videos from my desktop computer via USB onto my mobile, and firing them over to another mobile via Bluetooth.
In fact today I went and bought a Bluetooth USB Adapter/Dongle for £24.99. Now I no longer have to keep plugging in the USB cable, and the other mobile can now also communicate with my desktop computer. There's now even the added bonus of being able to operate my PC using my mobile.
I also got around to activating my ShoZu account and sending my first photo via them, to my Flickr account.
