Internal Antenna Problems

[JPBMW325]

Hey guys

So my pearl 8130 just started turning the radio off randomly and it will only go back on when i turn connections back on and then it will only stay on for a few minutes. I called bell mobility and they said its a problem with the internal antenna probably and that i need a new phones. So my question is does this sound correct? also if i have another pearl can i switch over the internal antenna or something like that?

Thanks so much

or is it possible to transfer all the internals from one phone into the other or are they all connected to the antenna? i just dont want to go into bell and pay the 20 dollar transfer fee if their is something i can do myself through a diy

EDIT: just did a diy on taking the pearl apart now i have the circuit board separated from the pearl if i transfer circuit boards do you think it will work or is the antenna somewhere on that circuit board
