Almost cool iPhone blogging

As a follow up to my last post, as near as I can tell you can blog via your iPhone through your gmail account. But you are limited to posting to only one blog. For example, if I have 6 blogs that I have setup, I can only blog to one of them! To create a blog posting I email go@blogger.com. Instead they should give me a unique address for each blog. For example: 3tg@blogger.com would post to the 3tg blog, ryan@blogger.com might post to my personal blog.
