How to make vCard QR Codes that are compatible with iPhone, Android and Blackberry

I've been working on a web page where you can scan a company's vCard easily on your smartphone and have it saved to your contact list. It's definitely a pain in the ass. Here is a sample QR code with a vCard in it:



Here are some tips:

• use the Image Chart Editor on Google Code - you have to look for the QR Code chart in the gallery. Basically, you send it a URL with the vCard in the querystring and it sends back a QR Code image. Don't forget to url-encode your querystring. 
• You don't need to email a vCard to iPhone, it can read them directly from a QR Code with the right app.
• I tried a few different QR Code readers for iPhone and most of them sucked at parsing vCards. The best that i found was Qrafter, and it's free.
• I used Barcode Scanner on Android. 
• Android didn't want to accept a URL, so I put it in the NOTE as well. Any tips?
• With Blackberry 6, use AppWorld, hit the menu, then choose Scan a barcode. 
• Blackberry can't read vCards directly from a QR Code, but you can qr-code a URL that returns a vCard. You'll want to send back this PHP header: header("Content-type:text/x-vcard");

Young, bored, and know Java? Please write a decent QR code reader for blackberry :)
