Android 2.2 running on T-Mobile G1
If you’ve got a T-Mobile G1 or myTouch (HTC Dream, Magic, or Google ADP1) and are comfortable flashing an alternative ROM, then you’ll be happy to know that the latest CyanogenMod (CM6 RC1) delivers some tasty Froyo. There are some reports of minor hiccups here and there, but the newer features and minor speed boost should make up for most glitches. As always, it’s your call and your mileage may vary.
