Rather then using a third-party app have you taken a look at Windows Live Mobile. It can be found by going to this link:
http://www.windowsliveformobile.com/en-gb/home/default.aspx
You can use this page to get Microsoft to send you a link directly to you phone so you can get the Windows Live for Mobile applications.
In case you are in the US here is the US link:

You can also go to the Windows LIve Essentials Mobile web-site at:

Or if you prefer you can just do a Bing search for "Windows Live Mobile" and it will be pretty easy to find. You can also jump directly to the Bing search for "Windows Live Mobile" by following this link:

Using the Windows Live Mobile Apps will be far better then trying to download a third-party app, as you know these apps are coming directly from a trusted source (i.e - Microsoft and Windows Live)
