Uhm, the news are just getting out. More and more news sites are reporting the problem. Just try a search on your favorite search engine now and in a few hours.
Yes, Apple has broken something in the latest firmware Out of curiosity I have just swapped the SIM in the SE for a Dutch SIM that can roam on all three German networks here. When you register it on T-Mobile and wait the indicator bars get weak after 10 to 20 seconds. Then the phone says "No service" for a few seconds. And now comes the interesting part. The phone then registers on Vodafone (tower is around 600 yards from my home) or O2 (also around 600 yards) and the network connection is completely stable on both networks.
The possibilities that your phones still work fine are probably:
- General network parameters set by your network operator still work with 14.7..1
- Some phones/base stations can have problems with a certain manufacturer of base station/phones
Yes, it is possible that the same phone can work on the part of an operator's network that has e.g. Ericsson base stations and fail on the other part that uses e.g. Huawei.
And BTW I was working as a network optimization engineer at a cellular phone company for 8 years. I don't need pointless post of "1st level support" quality.
