I have an app for my droid called anti-sms bomber that blocks multiple text messages so fuckers like you can't bomb my phone. they also make an app that you can download through anti-sms called SMS Bomber. it allows you to send as many text messages as you would like to someone's phone. you type in the text, enter the number of times you want to send (200, 300, etc.), and click send. it's the best way to lose friends. it takes a long time for 300 texts to come through to someone's phone. see ya battery.
what kind of phone/os platform are you working worth?
