Hey guys. After a long time of wanting an Xperia x10 I finally got one on Saturday. Before that I had a Blackberry Curve, so things are quite different from what I've seen so far. I have a few questions after fiddling around for a while; 1) Is there a way to set an .mp3 song as my SMS tone? 2) My phone came with some Moxier software; is there a way to delete these? I won't be using them as they don't appeal to me. 3) I'm using the built-in Facebook app, and I'm not recieving any alerts for notifications...do I need to do something for this to work? 4) Speech Synthesis - What is this and how do I use it? (I installed some voice software like it asked, but I don't see how this software is used) 5) I downloaded a task killer which was recommended; do they work? My battery drops so fast, is there other methods around this? 6) Finally, any useful apps you'd recommend to get the most out of my Xperia X10? I've seen various new keyboard apps which have tempted me as I have a little trouble with the stock one, for example. Thank you for your time. It's much appreciated.
