Subject: Re: Orange Spain disclosing user phone number

It would be funny to see advertisers send targeted SMS ads using this. I bet that the advertisers of web sites that participate in iframe ads would also get this information, assuming the Phone would load up iframe ads. 

I think the provider should fix this, because if someone developed an exploit similar to the one that was able to compromise the iPhone a while back just by sending a maliciously formed SMS message, your phone could be compromised just by going to a website where this information is sent to the web server.

I know this is pretty obvious, just my 2 cents.
