In the blink of an eye, XDA members Decad3nce, beezy420, and nfinitefx45 were able to port Froyo 2.2 w/ Sense from the HTC Wildfire to the HTC Hero. This rom is still in Alpha stages but is pretty functional for a port. It was ported from the HTC Wildfire Froyo leak and is only 80% functional as of today. More updates should follow soon, some of the features you can expect in this release are:

• Froyo 2.2 W/ Latest Sense
• Higher Screen Res.
• Newer Webkit (3.1)
• New HTC Keyboard

And other bullet points from Decad3nce himself

• Lots of bugs
• Port from HTC Wildfire RUU
• Not worth making front page

It shouldn’t be used currently for day to day use, but If you’d like to take it for a test spin yourself check out the development thread and flash it on your CDMA Hero.
