There is Skype out for BB's already, though its not really a full working version yet. I have it and it works on my Storm, but you cant do skype to skype calling yet, only chats are available. And seeing that the "pre-release" was made for BB's with keypads, I think the curve models to be exact, you can only use it in portrait on the Storm.
Search for Skype and Im sure you can find a download. If I can find one, Ill post it in here.
Any answers for how to get Skype onto the storm... I've checked iskoot, but don't see a version for the storm...
Check out an app called 'Nimbuzz.' I am currently using that on my Tour, and it handles Skype, Facebook, AOL, MySpace, Google Talk, Yahoo Messenger, and others. For some reason, Skype has declined to indulge Blackberry users.
