I just logged into XBox Live for the first time in a while today and I've mail informing me that XBox live is going to be offline tomorrow for about 24 hours. This must be the big update that was announced at E3. The blades will soon be gone and we'll have the more modern interface. I liked the blades but I'm very excited about new interface. I'll post about the new look once i get a look at it hopefully on Tuesday.
I've seen multiple reports on Google from people trying to login to Flickr through iOS 7 Settings and receiving the 'Could not communicate with server' login failure. I changed phones last week and received the same error message this morning. The fix that worked for me is:1. Go to Flickr through a desktop browser. 2. Go to the your profile image in the top right and click Settings. 3. In Your Account select the Sharing & Extending tab. 4. Revoke the iOS related Account Links. 5. Login again on your iPhone through Settings and you should now have access. I hope this helps. Usual disclaimer: please remember that this is offered purely as information about what worked for me. I do not accept any responsibility for issues that may be caused by anyone else following these steps and you do so at your own risk.
