After I began using Alltel's UTStarcom PPC6700, I found the power button only put the unit in the "stand-by" mode which would recieve calls. At the store, we tested two more that did the same thing and all the sales people were surprized. We call Alltel tech and they said this was the way the phone/PPC was designed and you could only change to a true off mode by removing the battery. So someone designed a phone that could only be taken on a plane, in a movie or in a meeting by taking out the battery?!! And Alltel sells such a thing?. Does anyone know if the Sprint or Verizon models are the same?
