I have the same issue when updating my iPhone 8.
It gets stuck til the battery runs out. I tried to recharge and turn it on but it gets stuck again.
Then I tried the TunesKit iOS System Recovery, somehow it solves the problem. I can reboot my phone again now and hopefully this helps.
Iphines generally take a few hours to update. If it has not made any progress, than you need to take your phone into the store.
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.
No, only an iOS update will.
There is no iPhone 3. You may be referring to the iPhone 3G or 3GS, which are the 2nd and 3rd generation iPhones respectively. Out of these two, only the 3GS can run iOS 6, while the 3G is stuck on iOS 4.2.1
Yes, you must be running at least iOS 2 I believe to use the App Store. Many apps will not support such an old version of iOS your phone is running so I would suggest updating to iOS 3 (the latest software the original iPhone can run) so you have more compatibility.
You can only recover lost apps from either iTunes if you have saved them, or if you have an iPhone that is capable of updating to iOS 5*, you can search for the app in the app store and you should be able to download it again for free as it should say 'INSTALL' where the 'Buy' button usually is. *You can update your iPhone to iOS 5 in iTunes. iOS 5 can only be installed onto the following iPhones; iPhone 3GS, iPhone 4, iPhone 4S.
Sadly, no. The latest version of the 3rd iPhone (iPhone 3GS) is iOS 6.1.5.
iOS 5 will be compatible with iPhone 3GS as well as iPhone 4.
It runs Apple's iOS mobile operating system. The first generation iPhone was released on June 29, 2007; the most recent iPhone models are the iPhone 6 and iPhone 6 Plus, which were unveiled at a special event onSeptember 9, 2014.
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.
Yes, you can run iOS 7 on the iPhone 4.
At the moment iphone 6 runs ios 8.1.3
The iPhone 5 will run iOS 6 or iOS 7.
