And start working by it self .. I mean out of 24 hrs its working for only 5 6 hrs a day .
for the information - when i brought this phone it was on 4.2 os and now i m updated to 4.5 and when i thought it could b a software problem so i totally removed the os and update it again with blackberry desktop software but nothing happened ... after that i have changed me carrier from vodafone to reliance but nothing happened .. then fianlly i m using idea sim but nothing has changed, BIS get disconnect by it self.
