The iPhone OS 4 announcement was monumental. It’s bringing the long-awaited ability to multitask along with some customization options, organization options, and new search and content management features all over the operating system. It’s a fantastic update, but not everyone will be reaping the full benefits. In fact, the majority of the iPhone user base won’t get to all those new goodies.

Apple has only approved the 3GS for a full OS 4 feature rollout. The original iPhone won’t get OS 4, period. The 3G will only get parts. Though it’s probably still worth it to make the upgrade, you’ll be missing the multi-tasking, the custom home screen backgrounds, and potentially some of the other processor intensive features. It’s not that big a surprise (though the wallpaper thing did catch me off guard) – the 3G has some trouble with the current OS – but it still sucks.

It points to a problem that has longed plagued Apple customers – the update cycle. For Apple as a company it’s worked quite well. What better way to stick it to your fanboy friends than getting the newest version of that thing they’ve been hyping to you for six months. Hell hath no fury like a fanboy bested.
