Take a look at the SDK. You can get the beta version free. Should you really need or want Flash, go grab a job at Adobe and make it
. LOL. The way I see it, you already have a portion of YouTube on there at your fingertips, you have the iTMS, you can stream video to it with things like that BBC player and others... Or you could make it easy and use iTunes for loading videos to it, like Bob said. Anything in the QuickTime format is easily processed and able to played in Safari should you encounter a QT movie. That said, what good is flash when a great deal of alternatives are at the front door?
I see the convenience of it, but really, you can get around it. QuickTime has plugins to play multiple different files, including flash files I believe, so if Apple decided to port some of those to the iPhone/iPod version of QT, you'd be set. But as it says above, Steve will not be putting it on there at the moment.
Being an iPod Touch owner, I can say that in some occasions, I'd like to have it, but as it only has Wi-Fi, I only use the web where I can, so it does not inconvenience me much. Plus iPods are primarily for music, so that's why I use it. We may see some incarnation of Flash with the introduction of the imminent 3G iPhone, but we may not know when that will be released. Some speculate June will hold all the answers by the looks of it. Wouldn't surprise me if a 3G update came out alongside the software update release and the WWDC. That would make sense since if it only took a couple of weeks to create some apps for the platform, you'd think they could start releasing some of them within the next month.
