There is word out that the Android Cupcake 1.5 updates for the G1 has been put out by T-Mobile. According to the Boy Genius Report, the news was contributed to them by some kind reader. Below you will see what bgr is saying exactly.

We checked ourselves and this is indeed the case but as some kind readers pointed out to us, customized ROMs can completely thwart a G1’s ability to receive the update notification. It’s not a hard fix to remove those cooked ROMs, so if you want to get your official cupcake on you know what to do. Oh, and let us know how it goes.
