I would really appreaciate any suggestions. I love my my touch slide but recently it is rebooting about 1/2 of the time when I try to make a call.(after I have put in the number and pressed the call button) Just as I begin to make a call it will reboot and the call will not go through. Then I will have to wait almost 5 minutes for it to restart and try my phone call again. At the same time I have to pray that it does not reboot again. Right now I have been forced to go back to my old G1 Iphone and I hate it. When I first got it (I bought it secound hand so I do not have the option to return it to the store) it only would reboot about once every 2 weeks, now it is every other call. Has anyone ever had this problem. I have seen similar problems and people saying it was sim related. Is this likely the cause. My sim was less than 2 weeks old when I got this and I have no problems with my iphone, just the slide. I really do not want to give up my slide. Someone said it may have something to do with the apps that are in the sim card and you can use task killer. But what do you do when the "task" is making the phone call?
