Yes you can use your domain registered with ResellerFly on Blogger, Google Apps or any Google Service.

Blogger offers two publishing options for your blog: hosting on Blogspot (example.blogspot.com) and hosting on your own custom domain (www.example.com or foo.example.com). You can change your publishing option at anytime, and your content will always remain unaltered regardless of which of these options you choose.

Before you move your blog to a custom domain, you need to have already purchased a custom domain (www.example.com). Once you have your domain name ready, our support desk will assist you in configuring Blogger. To begin, login to your billing account use the Get Support menu to open a new ticket to technical support with this request!

We may also need to have access to your blog account to do this.
