A few months ago, I made a deal with
the devil the worst and most obnoxious telecommunication company ever to get an iPhone, and I actually would not regret it if they did not bother me sending me spam SMSs when I am at work. This is so annoying and disturbing I would actually leave the phone at home, but I need it so my girlfriend who is pregnant can communicate with me. Here in Peru there is no such thing as regulation in the telecommunications market, so I actually cannot complain about being sent spam.
I am desperately in need of a mechanism (preferably one that does not require me to jailbreak my phone) to block SMSs from unapproved senders (or, at least, blacklisted senders). Unfortunately, the iPhone comes with no such functionality, and I have not found an app that does that (although I must admit I have not searched thoroughly). I would really pay money (up to, say, $5) for such an app. Does anybody know how to block SMSs from certain senders in an iPhone?
