I wasnt saying that was a solution to stop it but mostly the cuase of it for turning it off.
Now release 7.0.3, I turned back on iCloud, made a backup via iCloud, kept Passport disabled bc i don't use it, I kept iCloud Backup on, went to Software Update and updated and waited about 10-15mins.
So far, I have kept iCloud Backup on, and I have not run into any issues from the iCloud tab, the only thing I see which is odd to me, is when Settings is not open like close the app out from multitask, go back into Settings>iCloud and watch "Find My iPhone" from disabled to Enabled, why it does that, I have no idea and I noticed that in 7.0.2 few weeks later after being released.
Lots of improvements and others like alittle change on the home screen on your main 4 apps, some changes to the notifications on lockscreen. (not the scroll down NFCNs)
If it occures again, then I would turn off my iCloud Backup bc after only just turning that off besides Passport, I hadn't had any probllems with it since the last few days posting what i did that day.
PS. they wont discontinue support for the iPhone 5 bc we still have iPod Touch 5, besides the 5C/5S.. and they will still support iPod Touch 5 once iPod Touch 6 comes out next year. (iPod Touches every 2 years)
And by then, we will have iOS 8 and maybe iOS 9 if the hardware RAM/CPU can support it.
But will there be one? we just have to wait and see google results by Febuary/April/May/June of 2014
check out iMore & I know one other site i can't think of at the moment but they have the most accurect info for stuff like that for years
