I see (on O2 at least) I can now under Settings | Mobile | I can toggle 2, 3 or 4 G on or off. After a 6 week battle with O2 I now have my BoostBox but nice to know where 3G is poor I can switch to 2G now.
Since updating i can't get LTE on my iphone 6plus... I have the toggles for 2G/3G/LTE but can't connect to LTE its stays stuck on 3G... Did a reset network in settings and still nothing... Anyone else with the same problem?
