I bought one of those antenna boosters that go under your battery inside your phone. It was only $1.99 so I figured it couldn't hurt. It is nothing more than a plastic sticker with some metal on it. I put it in the phone. Turned the phone back on. Everything was fine. Checked my signal and it didn't seem any different. I put the phone back to sleep and when I went to turn it on to check something, I got nothing! It would not turn on at all. I plugged it into the charger and it turned on, showed that it was charged and then it rebooted. And then it kept rebooting. I took the antenna booster back out and now it seems to be fine again. (I keep turning it on obsessively because that scared the you-know-what out of me!) My apologies to those who told me that these boosters do nothing and don't bother. As it turns out, it DOES do something: it kills your phone! P.S. The apology is because I didn't listen to you. Lesson learned.
