That doesn't actually turn 3G off. There is no way to turn 3G off unless you turn on Airplane mode.
Anyway, I updated to 5.1 and have so far seen an improvement in battery life in the short time I have used it since. Hopefully this solved the issue, time will tell.
Hmm..... cellular signal remains, but cellular data is off. Try it out on your 4S. Go to Settings > Gneral > Network > Cellular Data and turn it off. Note that the '3G' indicator no longer appears in the top left of your home screen.
I just ran a series of tests on my phone, and these are my findings:
- I can send and receive text messages. I used a web browser client to send my phone a text message, thus eliminating any confusion as to where the text message was coming from.
- With WiFi on, I can surf the net and receive email. I don't get new Visual Voicemail notifications with just WiFi.
- I used my work phone to call my phone. I even see it appear on the 'recent' list.
Based on these findings, turning off Cellular Data turns off both 3G and EDGE data, but I still maintain some kind of cellular signal link. So, what I think Kris actually meant by '3G Network' is '3G data', not necessarily the cellular signal. Which would make sense if he was saying that he turns it on only to check mail, turning it off afterwards.
