This may be simple for IOS folks but I am not.

A user has an iPhone with IOS4. It's never been upgraded.

He now needs to go to at least IOS5 so he can our two factor authentication app.

I am concerned if he connects the phone to iTunes it will try to load IOS8 and that will cripple it.

Can you select which IOS to upgrade to in iTunes?

Thanks

You are unable to choose which firmware you can update to, due to restrictions put in place by Apple.
On an iPhone 4, the latest firmware you can update to is iOS 7.1.2

Hi - it will depend on which model iPhone this is. Anything up to an iPhone 4 will only be offered iOS 7 (maybe iOS 6 for 3G or 3GS). If it's a 4S or newer, AFAIK you will only be offered iOS 8. Anything upgraded via iTunes won't 'cripple' the device, but there is always a chance of something not being right with a new upgrade e.g. glitches being reported with iOS 8.0.1.

Apple control what version you can upgrade to by authorising the install to the phone - they call it "signing"

When they release an upgrade, after a while they will refuse to "sign" an old version, so you cannot upgrade ( or downgrade) to it,

As mentioned above the 4 is not included in the eligible models for iOS8 so will only update to 7.1.2 ,

It cant go to iOS 8, as the iPhone 4 doesnt support it.
IOS7 is pretty good on an iPhone 4, but you may need to wipe the phone and start fresh for it to work best.

Thanks to all. I will advise the user what to do. Hopefully he doesn't have to reset the phone since that is a pain.

Alas he did. While iTunes said it was backing up stuff it actually reset the phone he told me and he lost all his photos :-(

It's hard to provide system-wide backups for people's photos and anyway if they take photos on their work phones, then they should back them up themselves, either with iCloud, Google or just on the PC.

The one thing I always do before a backup/restore of an iPhone here at work is make a separate copy of their Photos. Usually chuck them on a DVD for them too cos I'm a nice Sysadmin :)

I'm not a sysadmin :-( But the ones that work for me didn't think about that. My view if it's a work provided device, then if you choose to put photos on it, then it's your job to save them. A bit harsh but my team has enough things to worry about to think about photos.
