My guess is it will be a while. A good working rom of 2.1 did not come out for our phones until there were Sprint leaks out there. I think the issue is with the hardware. Think of them like drivers. To get them to work with 2.1 they were able to see how Sprint did it and then do it similar to them. I am sure though we will see 2.2 in some form soon on the Hero, but just like the early 2.1 roms, you will have things not working such as the camera and so forth.

 

it's being worked on already [ROM DEV] N1 Froyo FRF50 Port Updated - xda-developers

 

Very nice! Obviously they have ALOT of work to do on it. Still ALOT not working. But its cool to see they are working on it. I can't wait for full flash on my phone!

 

Must say it is encouraging. Without a doubt, Google (et al) have figured out they have a winner with their design of Android (Java in a VM on top of Linux) and it is versatile and OPEN!! Third party support abounds and Apple is having nightmares about that.

The really big upside in 2.2 is the JIT compiler -- which will provide for significant speed improvement. That will be super!

Well for now, it is 2.1 and I have been trying to re-create some of the problems other users have had, and cannot. So far, 2.1.1 for me has been just fine. Although a flash to 2.1.2 will be in the cards soon.
