How to Manually select network on iPhone 3GS ?
I have recently upgraded my firmware from 3.1.3 to 4.1 and noticed that I am frequently getting 'No service' message. I called up my carrier and spoke about this issue for which he has asked me to switch the network setting from Automatic to Manual mode. I asked for the details on how to do the same on iPhone for which they could not answer. They have asked me to check the settings on my phone and configure it.
I understand that I need a option where the carrier network list is available and I need to manually select the carrier. I tried looking at the settings option on my iPhone 3GS, but could not find the same.
Can you'll please help me with finding this option / solution ?
Thanks in Advance
