I want to send malicious code in a friendly packet through text message.
Maybe it's an ex or the person from Craigslist that stood you up and won't stop pestering you to buy your old Atari 2600 set.
Maybe it's the guy that stole your app idea & is now in round 3 of funding from Venture firms, driving a Tesla, dating a russian model & guest starting on Silicon Valley (purely hypothetical, I'm not bitter!)

I would like to be able to have one button access to send a text message that will disable and then blow up the recipient's cell phone. Maybe turn on all the radios and full brightness at once while transferring files from internal to external memory. If you could do that that would be super killer awesome. I can think of a long list of special contacts in my folder that deserve to receive a text message like this.
Did I mention crotch burning as a possible in app purchase?
Thanks
