Sadly you cannot downgrade to an earlier iOS version. iOS updates to older devices should always tend to slow them down. If you think iOS 4 will slow down a device, iOS 5 makes the keyboard too slow to type on on my iPod Touch.
Considering updating your iPhone forces you to update to the latest software available for the device, updating an iPhone 3GS now will update it to iOS 6.
i dont think so, the latest update available for iphone 3g is 4.2.2 .
Click on 'Update' in iTunes!
The current latest iOS version on the iPhone 4S is iOS 6.1.3 considering iOS 6.1.4 is for the iPhone 5 only. iOS 7 will be available for the iPhone 4S this fall.
Simply update ios
No, itunes supports it.
You need to connect to to the computer that is authorised for your iPhone and update via iTunes.
iOS 6 is the software that was launched with the iPhone 5. You can run this software version on an iPod Touch (4th or 5th gen), any iPad except the original, and the iPhone 3GS, 4, 4S, and 5. You have only this summer to update to it if your device is eligible for an update to iOS 7 coming this fall. If you are running iOS 5, you can update to it from Settings>General>Software Update. If you are running any older iOS, you must plug your device into an iTunes-authorized computer to update. The update is entirely free by the way. You can see more about what features it brings on Apple's website.
You cannot. If you buy a new iPod or iPad or iPhone, it comes in iOS 4.3.3 and you have a choice to update to IOS 5 or not.
iOS 6 came out of beta September 21, 2012 with the launch of the iPhone 5. You can update to the latest iOS 6.1.3 (6.1.4 with the iPhone 5) by going into Settings>General>Software Update or plugging your device into an iTunes authorized computer if you are running anything older than iOS 5. If you are not fond of the iOS 7 update, then you must update to iOS 6 before this fall because after that, Apple forces you to only update to the latest software version or not at all. But you don't have to worry about this is you have a 4th gen iPod Touch or iPhone 3GS which can't get iOS 7.
Yes, if you update it to iOS 5.1.1, there is an untethered jailbreak out.
A guy unlocked my iPhone 4S from Sprint and he said that if I update the ios then I wont be able to use my phone. It's currently on ios 6.1.3. I know most things about iPhones except for unlocking and having to do with carriers.
