as I said, when my BB is on wifi works perfectly, once I disconnect wifi, BBm starts not receiving or sending...!!! it appears the o'clock or the watches.. and it takes time to start receiving or sending like 3 to 5 hours..
I have Curve 9300 3G software v6..
I'm on STC (Saudi Telecom Company) service.. I've called them many time but nothing new..
I've tried the host router table..
I've tried to turn off BB and take off the battery..
any help plz..
