3 must have apps on your windows mobile phone

If you are a windows mobile phone user, I'd recommend the following apps.

1) Fring - A swiss army knife for your IM and call needs.
2) IRIS Browser - A Webkit based browser from WM. Far advanced than IE from first impressions.
3) Google maps - Simply great, if you have a GPS embedded on your phone.

I upgraded my Samsung BlackJack 2 to WM 6.1 today and installed these apps , I love the phone once again :)
