I recently bought a storm Telus Unlocked version. I am currently using it on Vodafone IN.
The signal strength that I am getting is very weak(around 2 -3 bars). Before Storm I was using HTC GENE and I never got this problem.

Please can anyone tell me is it a network problem or maybe coz of TELUS OS.?

My About Screen Says:
Blackberry 9530 Smartphone(3G,CDMA)
v5.0.0.419(Platform 4.2.0.179)

Can I install the OS provided by some other service provider such as BELL Mobility or any other.
What all things should I take care of before updating my OS?

Please help me, I am a Newbie . Thanks in advance.!
