hello guys, back in January i switched over to verizon and got a droid incredible, everything has been good till 2 months ago. first phone started getting hot and wouldnt charge, verizon sent me a free battery, no change, then a phone. that worked ok. the second phone wouldnt get a signal, it would show no bars and switch between 1x and 3g all the time no matter where i was at. so i went thru there tech help, nothen worked. so they replaced it again. the third phone, which i have now, has the same signal issue, and also a crackly speaker, so i took the battery out, did a factory reset, re programed the phone, still no signal. verizon is sending me a 4th one out this week. is there something wrong with the phone or am i not just setting it up right?? any thoughts. i have a usb 727 aircard it shows all 5 bars next to my phone with shows 0. so im stumped.
