There's also another solution I didn't see anyone mention. All you need to do is setup a Gmail account, then go to Activesync on you Windows Mobile 5-6.x, in the server address you use m.google.com for the user id: username@
gmail.com pwd: your password and make sure ssl is checked, hit next then it'll ask what items you'd like to sync just make sure tasks us unchecked or you'll get an error code. then you'll have all your contacts syncd up. so when you go from WinMo to Android and sign into your account they'll never be lost. It also will always keep your contacts in WinMo whenever you sync to. If you have any other questions about syncing just pm me. I'll be happy to help in whatever way I can.
