So, should you upgrade? Always! You donāt have to right this second, but I would not skip a day without installing it. I recommend you monitor social media and websites to see if anything pops up before the day is out. Usually, these first updates can come with more bugs than they actually fix.
Anyway, let us know how it goes and tell us how well iOS 11 been running on your Apple devices so far.

Hello!
1) After upgrading to 11.01 (from 10.3.3. I wanted to wait a litle with the first version ha ha), my Ipad is rebooting every 1/2 minute, or less. I managed to upgrade to 11.02, but to no avail. After doing all I could get about it in the forums, I reset my device to factory settings! But… nothing, it still keeps rebooting. I wanted to downgrade, but now it is impossible. The maximum I get go back is to 11/01.
My Ipad is model MF121LL/A. I have plenty of storage available.
Please HELP!!
2) With my Iphone 6+, the problem after upgrading is very short time battery. But at least I can use it.
I thank you in advance for your help
