Within the numerous updates last night of Live.com and Live Search launching came a not insignificant revamp of the Live Mobile services, including:
– A beta mobile version of live.com is now available, something which got us excited a while back
– Mail and Search got "Orbed"
The mobile guys are doing some really cool stuff, so I'd recommend you taking a look at mobile.live.com in your phone when you have a free moment. Although the mobile search isn't the fastest and rarely returns me the most relevant results, I am always impressed with the performance and features of Mail for mobile. Definitely a must use for those on the move. The mobile webmessenger isn't bad either, with a client version on the way as well.
