External keyboard for iPhone 3G

[iffc]

Hello,
I need your gracious help... I just bought an unlocked basic iPhone 3G. I believe that there have not been any upgrades. I would like to use an external keyboard with it and don't care if it's wireless (actually I prefer it not be). Can anyone recommend one that definetly works with it (and where I can purchase one right away)? Thanks so much!

It looks like it takes a fair amount of effort to get a keyboard to work with it; jailbroken or otherwise:

I really appreciate your reply! Actually I'm looking for a full (or near full) size keyboard. There are several listed on ebay and amazon and, even though they list 'works with iphone 3g', it's not clear if there must be some upgrade required to the phone or some sort of minimum requirements in the phone software. Would any of these work? And, 'plug & play' -- not requiring some sort of hack to the phone specifically for the keyboard?
