Installing Android in Samsun Omnia M
It seems like a very long process and it seems like it is very hard to reverse:

From what I read you need to be pretty tech savvy to get this to work. If you have Ubuntu installed then it is a little bit easier.

You need to know how to partition a hard drive and things like that, if you are not very Linux savvy I would probably give this one a pass. If you are very Linux savvy or you are just dying to have Android then I will help you through it, but it will be a lot of instructions and it will take a very long time. And as with any non-official Android port, there are a couple of weird problems with it, but it seems they can all be fixed with work arounds.

I hope this info helped you, let me know if you decide that you are dead set on getting Android on your device. I will try to give you some pointers to help you along the way.
