What else is stuck on 1.x?
- Motorola Blur devices stuck on 1.5 are slowly going to 2.1, after which they'll be stuck there.
- The G1 is on 1.6 because of memory limitations.
G1 can be on 2.2 I've seen it myself. Backflip is on 2.1 but can't be updated to 2.2.
Eh, I don't think that's entirely fair argument though. Froyo on your iPhone 3G is probably not completely usable due to its instability, potentially missing features (due to lack of hardware buttons on the iPhone itself).
But that said, carriers' inability to upgrade their phones to the latest version of Android is fairly frustrating.
It's taking a while to learn the button layout (back is the sleep/wake button, home is the volume down, home is actually menu) but it isn't as laggy as I initially expected it to be.
you can root most of your android phones and then you can put any version of android on it that you want. Where is the difference? If you want to be sure that it works you have to wait for the manufacturer...
