@jason_mufc,
If the problem is only happening when you're at home and not when you're at other places then it must be the network. If it's appearing all the time and at different places then it's the phone!

@jason_mufc
It is possible that it is a Celcom Network issue; perhaps Celcom is doing something on their end? If they are, there will soon be a new "Network Settings"

@jason_mufc,
When the phone doesn't show 3G do U still get 3G connectivity speed or U don't? I don't haf the same issues with mine, thankfully.

@jason_mufc,
So when you're home you don't get 3G connectivity but EDGE? Or could it be that it doesn't show that you're on 3G but perhaps your connection is 3G connection? Is that possible?

I live in Sg Buloh too and don't have the same issues as you; then again, I'm on Maxis

@jason_mufc,
Good to know the problem's solved; must be the Celcom tower or something. I'm at the perimeter of Sg Buloh; nearer to Damansara Damai area
