2G (not 3G) internet not available when LTE feature button is available?
I everyone!
After iOS 6.1 (launched yesterday) 3G on/off switch button became LTE on/off switch button (only 6.1 turns LTE available for Europe networks, as you may know).
This way I can only use 3G (if LTE switch button is off) or LTE (if it's on).
No more 2G, as far as I can see.
The problem is: 3G drains iPhone battery very fast (3G and battery issues are far known, since the beginning), LTE even worst. I have wifi at home and at work, therefore almost everywhere, but I want 2G on to ensure I can receive/send emails even when no wifi network available. For this kind of usage I do not need 3G or LTE. 2G is more than enough. If I need other kind of usage I'll turn 3G, or even LTE, on. This way I ensure all services important to me are available without fast drain of my phone battery.
Disabling 2G switch is a step back considering that 3G and LTE battery issues, on my opinion.
There is a way to use only 2G or am I missing something?
(I own an iPhone 5 but I think this is more an iOS related issue)
