My main problem is missing out whole words. Something I never spot (no matter how much I check and re-check it) until after it's sent/posted.

Most times it's an obvious slip and people figure out word is missing. (See what I mean?)

The problem comes when it's a key word in the sentence that I omit. So, for instance, if I wanted to say - She's cleaned a dirty dog - it might end up being - She's a dirty dog...

Yep, I'd be up for that. I miss the old rainbow Apple logo.

Sounds good. But I wonder how many of these will actually work on the iPhone 3G. We'll probably just get the home screen background...
