S2U2 - Love the slide to unlock/answer
AIM - for WM I use aim a lot and its a full version but if you have a large friend list it gets laggy.
Google Maps - Yeah no explaination needed.
Windows Live Search - I like it for finding cheap gas and speaking what I want vs typing it all the time
TomTom 7 - Navigation
Star Playr - For Listening to my Sirius XM account Via Phone
SeeqPod Mobile - Great toold for finding songs and streaming them on your phone. You can also purchase the full song so you dont have to deal with the Stream.
SkyFire Browser - For sites that use Flash
Skype - For my VOIP calls and chitchat
Klaxon - a G-Sensor enabled alarm.
Diamond TV - Dont really use it uses a lot of bandwidth and isnt very smooth. When not roaming in a 1x(which I always am) It works great.
Diamond Tweak - Great for making some changes for your Diamond without trashing your Registry.
Lumos - Controlling backlight levels decreasing battery consumption.
Qik - Turn it on hit stream BAM your live online for the world to see. I Qik'd the birth of my Daughter(not the nasty part but the weighing n whatnot)
