Or if your iPhone is jailbroken & the signal strength no. is what you wanna know, can always install OmniStat for Notification Center from Cydia. Refer to the Cell IP...

so the signal bar is actually not accurate? even it full bar?

I read somewhere, it says the closer the number to zero, the better is your signal strength regardless of the positive or negative sign which just indicate direction.

So a full bar line should be around 0 or in the range of +- 10?

Uodate : I got -77 of full bar Maxis

Yup,lower the number,the better signal due to (negative).eg:-100 are weaker than -80.

The signal bar relates to the signal strength.

Using my iphone5 I notice something like this:

5 bar: -79 and better
4 bar: -80 to -89
3 bar: -90 to -99
2 bar: -100 to -109
1 bar: -110 and worse

2 bars of Maxis and -98. Sad.

best i can get is -69

Celcom 5 bars -68

Maxis -63 full bar.

-55 without 3G

Signal strength not related wif download speed right?

Yes indeed. You will get higher speed at full bar, if you are on just 1 bar 3G, your speed will be slower as well as unstable.

Wat problems r u saying?or u asking will this works on ur iphone 2g?

the best i can see is -51 for Celcom 3G.

try updating to 6.1.3?

updated, but did not feel any different yet. 3G still weak

anybody still trying?

trying what ?

trying to check the signal of their phone or testing the signal

when i tried on ios 7 beta 5 and beta 6, the signal strength wasn't accurate at all.

cause in good coverage area show -130, but 3G speed excellent fast. and always see -130, rarely go up to normal -70 -80dbm.

signal strong doesnt mean 3g connection is slow,its ability to receive line

but -130 is equal to no signal.

what i want to point out is, the signal strength is not accurate in iOS 7 beta 5 and 6.
