which way, i can know which type of iPad or iPhone i am using? like there is iPhone 4G and also 4Gs, so is there any way, means is there any code i use that on my dial pad and see the details together??
tricks n tips type. like the below:
Launch the Phone app
Dial *3001#12345#*
Then tap on the Call button, which will launch the Field Test app (or enter the field test mode). You’ll also notice that the signal strength indicator has switched to a number from the traditional signal bar.
Now hold the Power button until the red slider (slide to power off button) appears.
Release the Power button and press the Home button until the Field Test app quits
