How I confirm mobile numbers with Android (itsamit.com)

Thanks for sharing this. Outta the box thinking FTW! Is it possible to avoid customers having to pay for the sms? A toll free sms number maybe? I want to avoid my customers having to shell out for the sms, however small the number.

In fact in cases of international customers it could be a large amount.

Just thought I would comment here because I can't on your blog. The link to follow on hacker news just brings you back to the blog post.
