Where can I download software update ios 6.1 for my iPhone? I have a 64 GB iPhone 4s with Dual-core 1 GHz Cortex-A9 CPU and iOS 5. My iTunes always seems to be down so I can't update my iPhone. Any suggestions?
Hello!  I have iPhone 4G and I updated my phone’s software using iTunes. My wife’s phone is iPhone 4S and she updated her phone’s software using the Software Update tool under Settings. Try to follow these simple steps:
1.   Tap Settings.
2.   Tap General.
3.   Tap Software Update and your phone will tell you the latest software available and just download it.
In order to download the latest software, your phone needs to have a data plan or it’s connected to a wireless network.
