Yep indeed. Deliberate or not, AT&T is blocking access to Apple Maps, Beats 1, iTunes, and App Store.
Siri is also not working for me. The "genius" at the Apple Store had no clue what was wrong and suggested I get a replacement iPhone when I return from my business trip on Friday. Maybe I'll jump back to 9 until they sort out the issue, although 9 wasn't exactly working as a DD for me. Not having Siri and Maps working while driving 10 hours a day is a bit problematic.
