Should I get the iOS 6.1 update on my iPhone 5?

1. What changes are on there?
2. How many gb does it use to install it?

I don't know that's your decision.

"This update contains improvements and bug fixes, including:

LTE support for more carriers (complete list of supported carriers at www.apple.com/iphone/LTE/)

Purchase movie tickets through Fandango with Siri (USA only)

iTunes Match subscribers can now download individual songs from iCloud

New button to reset the Advertising Identifier"

It updates existing files and so does not take anymore space. The file itself is just a few MB.

Yes. If you have Wi-Fi connectivity issues it fixes that and at least for me on my 4S it seemed to improve battery life a bit. Also if you're looking to jailbreak your iPhone 5 then I recommend updating through iTunes and not OTA. The jailbreak should be released this Super Bowl Sunday so if you are going to jailbreak make sure to check out evasi0n.com

  • Update stopped during ios update own iphone now phones broke I connected my iPhone 4 to my computer (iTunes) and started doing the update through iTunes. About five minutes into the update iTunes in my computer stops working, causing the update to of course stop working. Now my phone will not turn on. On the screen it is black with the 'charge symbol' as if it were low on battery and an iTunes symbol. I have tried turning my phone off and on, but of course it didn't respond.
  • Should i update to ios 8 or stick with ios 7 on my iphone 5? Cuz from experience i know ios 7 is really slow on iphone 4. So just wondering if anyone already updated to ios 8 on their 5. Is it worth it, any issues with the speed
  • Should I update to iOS 7? Or Stay with iOS 6? I have an iPhone 5, and I was wondering whether iOS 7 is a worthy upgrade from iOS 6, and if the features are really that compelling or not. Or Should I stay with iOS 6?
  • Should I update my iPhone 4 to iOS 6 or leave it on iOS 5? I'm currently using iOS 5.1.1 because I didn't want to lose google maps (which I use a lot) to shoddy apple maps but I've seen a google maps app on the app store now so do you think I should update to iOS 6? And what are the benefits?
