Guys... I cannot find a Clear answer 2 this one. Does BBM work over Wifi? These are the answer's I have gotten. 1) No BBM does not work over wifi, it needs to go threw RIM's Servers. 2) Yes BBM does work over Wifi. 3) You need the service books to have it work. What is the case? I am here with a friend with 2 Sprint 9930's both have service interruptions (Please Contact customer support) 1 BBM still works and the other BBM does not.(Both on Wifi) 1 was always on the other was switched off. What I have found out is that if you loose service and switch to Wifi and DO NOT power off the phone (Which might cause you to loose the Service Book's) BBM will still work. If you power off the device and back on and turn on Wifi BBM will NOT work... WHY??? I have proof that 1 works on wifi and 1 does not, same phone same plan. I would just like to know the answer :confused: Thanks in advance
