Go Mobile
Mobile BlogSpot optimizes the layout of your blog for those reading your blog from a mobile device. To see what your blog could look like on mobile devices check out the preview functionality by going to the Dashboard > Settings > Email & Mobile tab.
SMS/MMS posting lets you send text, photos and even videos straight to your blog while you're on-the-go. All you need to do is send a message to go@blogger.com from your phone. You don't even need a Blogger account. The message itself is enough to create a brand new blog and post whatever photo and text you've sent. Later, you can claim your mobile blog or switch your posts to another blog; just sign in to go.blogger.com and use the claim code Blogger sent to your phone.
Email posting is another option to consider if SMS/MMS posting is unavailable from your mobile carrier. Find out how you can use the Mail-to-Blogger feature to post by email.
