I am having a problem that hasn't started showing up till I updated to 2.1. So, every time I receive a text message, I will get the alert with the noise just like it is supposed to, but then fifteen minutes later, my phone will make the sms alert noise again. Mind you, the second time that my phone makes the sms alert it is not because I am receiving another text message. What can I do about this? All help is greatly appreciated.
