IPhone 4 major slow down when "No Services" in subway
Does anyone know why my iphone4 experience major slow down on everything when I enter an area with "No Service"? Setting usually take 1 sec to open and it will take 10 seconds when I go under subway.
My phone is JB and I tried turning off everything (airplane mode + turn everything off) and same problem.
The problem gone by itself ONCE I went out of subway and start getting 3G signal back.
Any help appreciated.

So you're saying it's just slow opening/closing various apps? The phone could be searching for service in a No Service area and could slow down for that being its first focus rather than opening apps. When 3G is back (you're above ground again) it doesn't need to constantly be searching for service so that will not be a function slowing it down.
It is not only opening an app, the overall phone is crawling under "No Service".
It is getting obvious when I am watching rmvb above ground and everything was ok then it start cannot keep up buffering once I go underground.
I tried several rmvb player and it has same problem.
It seems the CPU is doing something else when I go underground.

What you describe sounds exactly like when I stream video from other apps. Or maybe the app is poorly written and it's codec decoding is not that great (if it's that resourse hungry). Maybe you should contact the developer.
