I would like to reopen this thread. The fact that the blackberry shuts its radio off is a very annoying thing as pointed out the originator of this thread. However it pales in comparaison to the fact that once you connect power to the blackberry, it DOES NOT let you turn the radio on, until the battery is charged for at least one half hour!
This is how it goes: I am in the middle of a phone conversation in my car, blackberry beeps, than radio goes off. Now I connect it to the 12v charger, but the device remains off because "battery charge is too low".
Can we at least change that? Why would it not allow me to use the phone when connected - that's ridiculous.
