Download iOS IPSW Firmware Files
Download iOS 7
Download iOS firmware (IPSW) files for iPhone (5S, 5C, 5, 4S, 4, 3GS, 3G, 2G), iPad (Air, 4, 3, 2, 1), iPad Mini (Retina, 1G), iPod Touch (5G, 4G, 3G, 2G, 1G) and Apple TV (3G, 2G). Firmware files are large so it will take a while for your download to complete. Firmware available for download on this site resides on an Apple Inc. server.
Checking Firmware Version
Use the following steps below to check which version of firmware is installed on your device. Tap Settings > Tap General > Tap About > Your current iOS firmware will be listed next to Version.
Update / Restore iPhone, iPad, iPad Mini, iPod Touch
After downloading the desired firmware, connect the device to your computer and select it in iTunes. Mac users hold down the Option key, while Windows users should hold down the Shift key. Then click on the Update or Restore button, select the IPSW file you recently downloaded and click Choose. Your device should now begin to update. Certain browsers may change the ipsw-file into a zip-file. If this should occur, just rename it to end in .ipsw and iTunes will recognize it.
Restoring your device will delete all data and content, including videos, songs, photos, contacts, and other important information. All settings will revert back to factory condition. On the other hand, updating your device doesn't affect your content, settings or other information. It's always a good idea to back-up your device using iTunes or iCloud to recover your data just in case something should go wrong.
