For over a year now, I have been using mobstac to power the mobile version of my blog because it allows me to display custom and google ads to people that read my blog with Opera mini and some other mobile browsers.
If you're monetizing your blogger blog with Google Adsense and have activated the blogger mobile template, anyone that visits your blog with Opera browser will not see any ad on your blogger-powered mobile site. Just imagine how much money you will be losing if high percentage of your mobile traffic use opera mini browser.
Hence, if you want to be making money from your mobile traffic especially those that access your blog with opera mini, you have to use mobstac and ensure they only see the mobstac version of your blog and not the blogger-powered mobile site.
If you want your blog readers to see your mobstac site instead of the blogger mobile template whenever they access your blog on their smartphones, all you just need to do is to add the mobstac redirection code to your blogger html and deactivate the blogger mobile template.
For you to add the mobstac code to your blog's html, you must have an approved mobstac account and you must have set up "m" subdomain for the mobstac site eg m.ogbongeblog.com. Hence, if you are still using www.somename.blogspot.com, you will have to change your blogspot to .com to get started. I can set up a custom domain for your blogger blog if you don't know how to get it done.
To deactivate blogger mobile template, log in to your blogger dashboard, click on "Template". Click on the settings icon under "mobile". Select "No. Show desktop template on mobile devices." and SAVE.
I hope this helps.
