If you have java (J2ME) enabled mobile phone and you're looking for great and free software to downloads to your mobile then go to http://www.getjar.com or wap.getjar.com and download away. A whole bunch of free and trial games and software you can download to your heart contents!
I have been busy browsing through the sites for the past 2 days and there's still more to go through. The only problem for me is my mobile phone memory is gettting smaller and smaller by the day. There's simply too many of them!
Well, I'm going to look for more stuff over there right now. See you there!
