i am not picking up any signal at all on my TP it was working fine before i went to class but after i got out i have not been able to pick up any service whatsoever, even in areas where i get perfect signal (the antenna icon has a screw looking icon next to it). this is the second time i had to hard reset it for it to start working again, only a matter of time before it does this a third time any suggestions to prevent this from happening again?
