Those of you that haven't been on Mars for the last month will know that the new T-Mobile G1 Android phone is coming on 30 October, and from launch there will be 50 free apps for your mobile pleasure.

Many of the free apps are the fruits of Google's Android Developer Challenge, which was designed to get the top developers from the community exploring the possibilities of the new OS.

We all know that paid-for apps are coming in early 2009, and some of these might make that list, so get your hands on them now while they're free and hot. Well, not now, in around a week. Otherwise it would be difficult.

Anyway, here's the list in full, so breathe in and check out all the application-y fun you can have on your G1... we especially like Android Says, though we haven't been able to find out what it is yet. If you developed it, let us know!
