Did you know that you can compose a blog post on your phone using an SMS text?
This is pretty cool the way it's working for me. Of course, it has its limitations like lack of formatting or the ability to add an image (it's not MMS).
Probably the best part is that it's free. Right now I'm composing this post on my iPhone 4S. If Hubby weren't sleeping right now, I could even use Siri to dictate this text.
