For those of you who are bored with the standard windows interface and dont want an iphone....try winterface! Its absolutely free to try for 14 days!
I had a few problems downloading it initially but finally got it installed and it was we worth the agro! You can pretty much customise it as you wish and i will tell you on the icons themself if you have a new sms or missed call for example. You can also choose what icons are on what screen and even hw many screens you want.
Well worth the trial and I'm sure you will want to purchase it afterwards.
I'm running mine on my new Samsung Omnia and it works perfectly. It can be downloaded from http://iwindowsmobile.com/vito-mobile-shell.html
Enjoy!
