Web Developers → Facebook - attractive apps?

Hello guys,

I am trying to overlook a facebook fan page with thousands of users. I want to be able to integrate a tab in this fb fan page from where people can send SMS to mobile phones (for instance something similar like this »www.mobile-sender.com) is this possible or not?
Any company, application, ?
I also want to create customize tabs like welcome tabs, games tab, etc? which application would be good for this? I was checking SocialAppsHQ, but maybe you guys would know something better?

I want to make this fb fan page more attractive and be able to integrate new things.

I look forward for your reply.
Thanks

I know you can send sms from gmail. Not real familiar with how you would set that up easily using a form like that..Pretty much anything that you can run in a web browser you can turn into a fb "app"

Like i turn a basic java script into a FB app page via iframes.

Check it out.

Probably can, I know over the past year in development with Facebook PHP SDK it's just practically an iFramed "window" with Facebook permissions accepted by the user. You could even go as far as integrating it with the users SMS service. There is a permission for that.

To see what I'm talking about here is my weather app I have been "tinkering" with:

Then in Facebook "frame" https://apps.facebook.com/arweathalrt/

I recommend going to the Facebook frame first adding permissions then stepping out of the frame to see what I'm talking about.

Sometimes because I refuse to ask for "Offline Access" the out of frame app doesn't work like it is supposed to.
