Kim, I'm not fully up to speed with those smart phones myself, but my wife has one. From watching her work with hers, it seems the phone has a "facebook app" on it. And that is what's asking you to upload it. So by that logic, you'd need to get a 'southern airboat app' (I'm sure one is not available).
Now, maybe, if you can log on to s/a from your phone, you can go to the gallery, find the upload link, click it, and follow the standard steps which as Scotty was talking about: you find the location of the image file (jpg) usually with some sort of "browse" button. Then choose the photo and tell it OK which starts the upload.
Those smart phones are getting more an more popular. Laura loves hers - she reads probably 80% of her email on it, and 50% of her facebook is from her phone. We sit in a restaurant, have a debate about if a plane could take off on a conveyor belt, and she'll go online and find the answers. LOL It's great. I want one too!
But I'm pretty sure you're gonna need a "s/a app" for the phone to do any direct uploads. It's up to Rick to decide if that's even possible. Pretty cool if it is though!
Good luck.
matt.
