OK... This is my wifes phone. Samsung infuse. She is coming from an iphone 3 and she and i are a little lost on these couple of things. 1. We have downloaded several apps to try and get different ( louder ) SMS tones, songs anything..... She works in a loud enviroment and she can not hear ANY of the pre loaded notifications. all of the apps say set as notification and it does change the email alert but we want and need the text message aleart to change. Please help us with this in DETAIL we are both newbs when it comes to the droid user interface.... Thank you in advance.
