I recently got an iphone 3gs the firmware is 3.1.3 stock so I can't jailbreak the phone. My job requires that I am on call and I receive the pages through a text message on my phone. None of the sms tones on the iphone will wake me in the middle of the night. As of right now, I am changing back to my Blackberry at night. I have tried two of the sms apps but neither would let me create a tone. So, my question is does anyone know if there is an sms app that allows you create a custom tone or any that have longer tones. Thanks!
