Yep. It's none of the things you said. Hehe! Wow I might actually get to play!
How do I post from my blackberry?! LOL!
Basically, here's what you do:
1.) Take picture with BB.
2.) If you're really really worked up, you can post a message from the BB saying "I got it! Will post screen capture in 10m!"). Though no idea if anyone would honour this. If you can get home quick enough, you can actually use your computer to edit your own post and add the picture.
3A.) - Send picture as email (make sure resolution and size were low) to a hotmail/gmail/yahoo/etc email account, and then download that picture from there to your computer.
3B.) - Plug your device into the computer, and it should give you a removable storage that you can go into and get the picture.
4.) Upload the picture to a Photobucket account (either yours or someone elses, like when Jaxman claimed the Pork Shoppe, but had me post the pic, by posting you have it and then having the other person post it)
5.) Create a post with the image linked in.
There's no way to directly upload the picture from the Blackberry to Photobucket/GTAM that I know of, though I could be wrong, or there may be an app for it
