I am still setting up my 4S and have run into two problems so far. Firstly, there is no option to switch off 3G when I am not using data. This is a big deal, not only because of battery life but also as I understand 2G is less harmful to the body than 3G. Secondly, I can't set up my POP Gmail account. On my 3GS 4.3.3 I was using it with the recent: option as most of my emails are stored on my iMac and it worked perfectly. Now, I am unable to type a colon in the relevant place, the option just isn't there on any of the keyboards, and then, when I copy and paste one in, the email address is rejected when it tries to verify it. This makes no sense at all as my iMac still uses the same recent: and works fine. Please help, has anybody any solutions?
