This will only work if you're with T-Mobile.

EDIT: You don't have to be rooted.

 

You have to do it manually. The instructions are on the link.

It's really easy as long as you can follow directions.

 

you have to do that all manually

 

Non-rooted is only for the tmo group... If you are on AT&T, you will need to root to get Froyo - there are instructions on xda developer forums.

 

Don't do it just wait for the official release. Too many bugs.

 

I don't know if I'd say TOO many bugs. There are some weird things, but I'm enjoying running it. The speed increase alone is worth it. But if the OP is new to Android, I'd suggest waiting as well.

 

Sorry, too many bugs is a little strong......

There are a couple of things I have noticed but it is a usable ROM in day-to-day use.....the Modaco kitchen version includes a Market fix as well.

 

Disagree, I find it to be excellent.

The only odd thing mine has done since Saturday is charge really slowly once.

Just be prepared for a slightly limited market due to lack of FRF50 fingerprint.

 

You can fix the lack the market issues if you root your phone. There is a thread on xda to mod the build.prop files so that they Froyo looks like Eclair to the market. I have been able to get all my 'private' apps back which has allowed me to stay on Froyo until the official release comes out.
