iPhone 4s to iOS 8 - its a Go-Go

I have upgraded my old iPhone 4S to iOS 8 a few days ago, and I can tell you with confidence that  it is safe to upgrade your device too.

Despite a tiny flaw, I didn't find something that could affect in any manner the decision in performing the upgrade. I didn't find in any way a battery drain bigger than the actual drain I already have with my original old battery.

There is something else, that you will need in order to upgrade to iOS 8 other than the will and desire to do it, and this is patience. The complete upgrade will take over 2 hours.  

Before downloading the iOS 8 you will need to remove as much content and applications as you can (specially if your iPhone 4s is a 16GB iPhone) since you will need 4.5 GB free to start the process.

Free at least 4.5 GB to get ready

After removing all that content, you will be able to start the download and not before. By the way, the 2 hours process did not take into account the time you waste removing photos and apps.

Press Download and Install

After Pressing the Download and Install, just forget about your phone for the next 60 minutes...
