It was already said earlier that the upcoming Android version would not work on the original Android phone, the T-Mobile G1: the memory space would simply not be sufficient. A developer has now proven the opposite: Android 2.0 runs on the G1, and apparently also "fast and smooth". This means that Android 2.0 is no longer exclusive for the Motorola Droid or Milestone, which will be released tomorrow and is the first device to officially feature the new version of the Android operating system for mobile phones.
This was made possible by the Android 2.0 source code release from Google, so that the software could be adapted - after all, Android is largely (except for extensions) open source. And that's a good thing, after all it makes for a better spread of mobile internet.
