I just got a new MacBook Pro with the current version of iPhoto, which supports Photo Stream. I have an iPhone 4, but never had Photo Stream enabled because my previous computer couldn't run the version of iPhoto that was required to use it.
Anyway, I just enabled Photo Stream now, but it seems that it only includes photos that were taken after I enabled it. I have 350+ photos in my camera roll that I'd like to also include in Photo Stream. Is there any way I can import them or something?
