The big brains over at XDA-Developers and PPC Geeks have been working on ways to port leaked versions of Android to current HTC phones. They've been doing some pretty amazing things so far, but due to technical reasons, it required a lot of RAM to boot.
More specifically, this "hack" required the OS to load from RAM over Windows Mobile, since it needs the hardware drivers.
This is fine for devices with 128+MB of ram, that give you plenty of space to load into even after Windows boots. However for devices like my trusty Sprint Mogul (HTC Titan) with only 64MB, this was filed under "not possible".
But some PPCGeeks forum members (l33tlinuxh4×0r and dzo) have managed to get it to boot and be functional despite the limited RAM.
“Android boots, The touch screen works. You can make phone calls. You can browse the internet.
This will NOT mess up your phone. It runs from ram and there are no permanent changes.”
