I was wondering several things
1.)I can't find much information on the story of stormhold and dawnstar at all other then whats at UESP which doesn't elaborate on the plot. was there more to the storys?
2.)I know the phones you had to have to get the games but what did you do download them or did you buy something? and are they still offered? die hard Elder scrolls fan and don't want to go out and buy a phone to find out they no longer provide the games.
3.)is there a computer version of the games?

I believe they're downloaded from your carrier. There was a physical copy of Shadowkey, but I think it's an exception. You'd have to contact your carrier for information on their availability, particularly since the phone lists we have for them cover really old phones, and it's possible that some newer phones are backwards compatible and can also play them.

There are no computer versions of any of these.

As a side note, shadowkey is a game for the nokia N-gage. Stormhold and Dawnstar will also run on the n-gage. unfortunately my carrier did not offer Stormhold and Dawnstar (small local cellphone provider). with a lot of searching and a very high luck stat, I was able to find them online for download. long story short - if you want to play them all, get an N-gage.

{edit} As I just found out, the n-gage will NOT play oblivion mobile.
