No its not. What a blanket remark. 7.04 is working just fine on my iOS devices
It's actually true. I've seen more people than not, having issues with the iOS7. Both personally, friends and such, and people online like on this forum. 7.0.4 has been terrible on my 5s. Resprings about 3 times a day. I've seen this on 5s's fresh out of the box as well. Sick of it to the point where I paid the 99 bucks and got a developer account last night just so I can get 7.1 beta this morning.
