Oh dear, found the app
I'm not sure why I never thought about Blogger having an iPhone app. I can't exactly claim to be non-tech savvy. I've written two iPhone apps after all.
I just don't tend to think tech when I'm at home. I don't use tech much. I read paper books, not a Kindle. I don't do downloads. I don't play games. I avoid Facebook as much as I can.
And now I find an app for this. Oh well, I'll have to try to not spend too much time on this thing.
