At this point, I’d be surprised if anyone still thought that the ‘Godfather’ of Android devices – The T-Mobile G1 – had enough juice left in them to make Google want to aim their latest and greatest at it. While the Android team wishes the G1 could still keep up with the Joneses, they’ve formally stated that Froyo would never be officially adapted for the phone.
That doesn’t mean all hope is lost, however, as the Android team has also assured us that – thanks to the unaffiliated development scene – the G1 is still technically capable of running Android 2.2. Those who root their phones have probably become familiar with the Danger SPL: it’s a custom SPL that repartitions the phone’s flash memory so you’ll have more space to install bigger operating systems.
The biggest problem with Froyo on the G1 seems to be the space, though, as the Android team told Android Police at the Fireside Chat that Froyo was built with the slower processors in mind (as we saw Google allude to when they announced that the JIT compiler would be implemented for Dalvik at Google I/O).
Google’s stated that if you do want Froyo, then you’ll need to be looking at developers like Cyanogen to cook up a solution for your antiquated (but still very capable) hardware. Whether or not Cyanogen takes up the challenge remains to be seen, but I think you owe it to yourself to start thinking about buying a new phone, at this point.
