Gingerbread will appear in AOSP soon after Nexus S ships
Some of you might wonder what this means, so let's clarify that having the source code on the Android Open Source Project means that custom ROMs will follow suit and you will likely get Gingerbread on your rooted device sooner than you might have thought. And this would be just about any sweet DROID or other Android-flavored handset.
Now, you might still want to check out if some minimum hardware requirements would appear for the latest Android release (not that we expect this to stop you), but for the time being it seems that most phones will be compatible. And given that even older devices like the T-Mobile G1 squeezed Froyo, we are hopeful that Gingerbread will be running smoothly on older phones as well.
