Harold,
I'm not sure if you have found something that you like yet, but I've used these guys for awhile after trying some other apps: iPhonethemeforpocketpc dot com
It's probably the best use of Wisbar that I've seen. There's a lot less hassle with files, but it still gives you control over how you can customize it. They've got great support and future add-ons are free.
BTW, make sure you have activesync. I didn't when i first got my treo and it was such a headache trying to get all my contacts and things matched up.
