That's all Cupcake - Android grows too large for G1 | - Betanews
The simple fact is that there is not enough memory on the G1 to support a much bigger OS, and even equipping the device with Cupcake was reportedly problematic. "We knew that internal flash space was going to be very tight on the G1 and we kept the system partition tight on purpose," Jean-Baptiste Queru, a software engineer at Google said on Twitter last week.Even though T-Mobile continues to deny it, the Android community has resigned to the fact that the T-Mobile G1 (also known as the HTC Dream) will not receive any significant upgrades beyond "Cupcake," the Android software update from last April.

There comes a time when the latest ROM upgrade just doesn't cut it. So much for the G1... No more Android updates for you! Its only been like 6 or so months for this device (give or take a few); and its already being obsoleted? If I were a G1 user, I'd be ticked off!
