Google Android 2.2 shown running on a Nokia N900
I’ve been using the Nokia E73 Mode as my primary T-Mobile device for the last couple of weeks and as awesome as the N900 is I am finding the utility and ease-of-use of the E73 Mode to be more compelling at the moment. If you are bored with your N900, then you should check out this Android Central post that shows Google Android Froyo 2.2 running on the N900. There are definitely limitations with the build at the moment, but it is pretty slick it runs as well as it does.
I wonder if the issues with the SD card mounting have to do with the fact that there is an integrated flash drive on the N900 since I have seen issue with apps on the HTC Incredible (one of the only Android phones with an integrated flash drive). I am pleased enough with the N900 and Maemo while also having my own Sprint HTC EVO 4G that I do not plan to attempt this port. Any readers try this out? Keep in mind, I am NOT recommending it and just thought it was pretty cool that it is possible.
