This site provides download links to ipsw firmware files for all Apple devices including i Phone 6 Plus, 6, 5S, 5C, 5, 4S, 4, 3GS, 3G, 2G; i Pad Air 2, Air, 4, 3, 2, 1; i Pad Mini 3, 2 with Retina, 1G; i Pod Touch 5th, 4th, 3rd, 2nd, 1st Generations; Apple TV 3rd, 2nd Generations. Updating your device doesn't affect your content, settings or other information.
Firmware files can be very large in some cases, so it may take some time for your download to complete. In either case, backing-up your content in i Tunes or i Cloud is recommended.
When you have an OTA update waiting for you, your Settings app typically gets a red badge and i OS will constantly nag you about software updates.
The thing is, not everyone always wants to install Apple’s updates.
Just click on the blue OK button and move on to the next step. Now that you’ve effectively closed off OTA updating on your i OS device AND deleted the OTA firmware that was already downloaded (if it was), you should be in the clear and i OS should say your firmware is update to date even if it’s not: Since my i Pad now thinks that i OS 9.3.3 is “up to date,” I will no longer get prompts to download and install i OS 9.3.4 or later unless I connect to my computer and open i Tunes, which really isn’t very often. Now that you know how to disable OTA updating on your i OS device(s), you can keep your firmware right where you like it without being badgered to update it all the time.

I’m an i Pad2 GSM user, and I guess I bought it around September 2011 and even after so many iteration (i Pad mini, i Pad 3, i Pad4), I decided to stick to i Pad2, as I have minimal use of i Pad.
