iPhone 4s 5.0.1 problem - Signal full but 3G network keeps dissappearing inside the house and showing only 'o'.

I keep having the above problem that annoys me a lot. Although signal is showing at full bar but 3G network is almost always dissappearing inside my house, leaving me with an 'o' symbol. This doesn't happen with the iPhone 3G and my 4 y/o Nokia where the 3G symbol is always there. I've done all, restore firmware to 406, reset network settings, etc. But those don't seem to work.

Any ideas how this happen? Any suggestion is much appreaciated. Thanks.

iPhone 4S, iOS 5.0.1

I went to my carrier and changed the SIM card, then I trimmed it in a certain way to a micro SIM. Inserted the micro SIM card and Voila, problem resolved. 3G is coming back to Papa in da house. No more dropped signal.

So my conclusion: the way you trim your SIM card into a micro SIM really does make a difference to iphone 4s signal reception.

So I am guesing probably the iPhone signal reception issue came from the iPhone SIM card reader itself not adjusting to the SIM chip.

OK, here is the trimmed micro SIM card comparison:

Hope this helps!

This is not the problem in my case. I didn't cut down my old SIM card down, I bought a micro-SIM card from my carrier, Rogers. And I'm still having the problems. Even with the 9A406 build which did nothing to fix this problem.
