SproutMobi allows you to choose 2 ways to create your own mobile website. First, convert your current site to a mobile site. Second, create your mobile site from scratch. This option is the only one you can choose if you want your mobile site to show on a different domain. SproutMobi will even give you a subdomain if you don't want to register your own domain.
The site creating process is great and very easy. Everyone can create a mobile site in no time with this mobile site builder.
