Is iPhone 4S software update iOS 6.1.1 free?

Is iPhone 4S software update iOS 6.1.1 free?

Yes. A restore/upgrade is as simple as plugging your iDevice into your computer, opening iTunes, and selecting "Check for Update."

Alternatively, if you're running anything over iOS 5, you can head over to Settings > General > Software Update on your iPhone and update through OTA (over-the-air) updates.

Yes the software is free. Just go into settings and check for the update

Yep, at least yes if you update it over your computer or over Wi-Fi. If not then it will be downloaded by your cellular data which depending on your data plan might cost some money (but really the 25 or so mb won't do much to it)

Apple don't charge for ios updates as you've already paid a lot for the device

I would recommend plugging it into itunes and doing a backup before you upgrade, justin casee anything goes a little wonky
