I just got this phone yesterday. I needed a solid all-around phone with a few would be nice features for occasional or future use (camera, bluetooth). But even after one afternoon, I got to know that most annoying PTT button. After scouring the web and finding the needle-nose pliers solution, I found a few comments about locking the PTT key - but no solution. But here it is: Menu>Settings>Locks>PTT Key Lock>On. Woohoo!When you press the PTT key now, it says "PTT key locked. blah blah blah..." on the exterior screen, but when you open the phone, you do NOT get that "Do you wish to initialize PTT?" screen.There are still some times when that screen comes back (I think if you press the volume up key and then press PTT), but it has significantly reduced the number of times I've had to press the "No" button. And once the phone goes back into sleep mode, it reestablishes the lock.
