There are loads of demo's available.I will put them up once I'm managed to check they work on the n-gage,(so if you download from here you'll know they actually work), some are buy via text messages,some are buy from developers site, so I'll put link to site if I have the information.
Warning ; Dont load the demo's on to your n-gage until your ready to try them, accessing a game counts as a go with some time limited demo's!
