Blogger mobile templates are mobile-optimized versions of our Template Designer templates. If you are using one of these templates, when you enable the mobile template option your blog will begin rendering using the mobile version of the same variant. Even if you are not using a Template Designer template, or using a heavily-customized version of one, you can still enable this feature to have your blog start rendering in a generic default mobile template that we have created.
Some of our feature highlights:
We hope you enjoy the mobile templates. As always, we would love to hear from you so please let us know what you think through our feedback form, and stay tuned for future improvements.
