Without a Blackberry Data Plan, you CAN NOT use BBM. Will never happen, nope, nada, ain't happening man. So no BLACKBERRY data plan (no other data plan will work btw), BBM is not working, no hacks to make it work, no way to fake it working or trick the phone into thinking it has a BB data plan.
So in answer to what you can do to get BBM working, the ONLY way is to get a Blackberry Data Plan. Sorry but it's the only way, since all BBMs go through the RIM servers when Blackberries are connected to BES (BlackBerry Enterprise Server) or BIS (BlackBerry Internet Service). But I can use Wifi you say, yes, yes you can use Wifi for internet access for anything but BBM and any app that must have BIS or BES to work.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
