I got the version for iphone 2G (iPhone1,1_3.0_7A341_Restore.ipsw). It installed fine with no issues. But I've noticed a lot that doesn't work. Visual Voicemail is broken (for now). Also I cannot find the MobileMe settings for 'find my iphone'; it may be disabled since I don't have GPS. Also A2DP (bluetooth stereo) doesn't seems to be working yet. I don't know how you would go about selecting bluetooth stereo headphones in ipod mode??? It has always seen my motorolla S9 headphones, but doesn't function any differently with them now with 3.0. I'm worried that the 2G is going to be cut off from more of the features as time goes on.
