Does iOS 8 really need 3 to 5 GB free space; request tips on least painful way!

[Subu]

Dear All

Good day / evening folks

I understand that iOS 8 is approx 1 GB in size but may need 3 ~ 5 GB space to unpack etc. that's too much space on my 16GB, iPhone 5 !!

What's the best way to backup + delete some music, make space, install iOS 8 and restore the music ...

1. I have a PC with itunes (albeit ) old version installed

2. I have a hotmail / 1 drive account with 30 GB (thanks to the recent upgrade)

Tips and trick to do this with least pain / loss (either PC or 1 drive option ) are most welcome


thanks
regards

It needs it for the upgrade, but not for running.

Use iTunes and upgrade from there? I'm sure I read that doesn't use the space on your device, but the untethered upgrade is so easy it's almost painful to revert to using a cable. Now, if you're running at the full 16GB already then there could still be issues I guess.

edit: never mind. I'm guessing you'd need the most recent iTunes for that to work. Must concentrate more when reading threads

My slightly old iTunes also shows me an update pop up ... but it itsn't working so far. I've posted my problems here
