Just finished installing android froyo onto my old iPhone 3G. As u can see from the clip, there is a bit of lag and is a bit annoying to use.
From what I’ve had a play with so fat, it seems to work fine, the camera doesn’t work, though wifi does so that great. I don’t have a normal sized sim to test the phone feature, but I’ve heard that it works.
One drawback is the lack of the android market place, but that is due to permissions, and the guys that have hacked this together more then likley wont get permission. There are some hacks that I’ve seen, but they seem really complex, and personally, I not going to waste my time trying.
Also, when it goes into standby, there is this annoying continuous clicking sound.
Here is a little video clip I made from my iPhone4 showing my iPhone3G starting up andriod.
