HT4972 I am using IPhone 4. I want to update my IOS 4.2.1 to 5.1.1.

Hi,
I am using IPhone 4 with IOS 4.2.1
Most of the apps cant be installed in IOS 4.2.1
I want to update to IOS 5.1.1.
Please guide me.

You can only update to the current version. For the iPhone 4, that's 7.1.
Are you positive you have an iPhone 4? What does it say in Settings>General>About>Model?
4.2.1 is the last version of iOS that will run on the iPhone 3G.

iOS 4.2.1 is the latest version of iOS for the 3G.
Facebook and Whatsapp both require 4.3 or higher.
If you want to use those apps, either use the old version that should be in your iTunes library or upgrade the hardware to a 3GS or newer device.

I have an IPhone 4,with IOS 4.2.6. I just got an iPad which has an IOS 5.1.1. I want to update my IOS on the phone but the computer I use no longer has Internet access. How can I update my phone? Also, what iTunes version should I have for the updated IOS

I have an iPhone 4 with IOS 4.2.6. I recently received an iPad with IOS5.1.1. I want to update my IOS on my phone but the computer I use is no longer hooked up to the Internet. What do I need to do? Also, does my iTunes need to be updated? It is whatever was available last July. Thank you for your time and courtesy!

To update your phone requires using the latest version of iTunes, on your computer, as well as Internet access. The update to iOS 5.0 or higher is an erase/restore deal, so you not only have to make sure all of the content, currently on your phone, is on your computer and accessible, you need to update iTunes first, have Internet access, then update your phone. There is no way around this fact. You could go to an Apple store or use another computer, but you run the risk of losing all of your data it you do that.

You need to purchase a newer model iPhone.

HI, Im using Iphone 4 and i recently got my IOS updated to IOS7 and now im getting the error message as "PDP authentication failure" Im using Aircel carrier.
Please let me know how to fix this issue

update...
I am not one to give up. So I called AT&T today. Now they are telling me they canceled my order because they were unable to fulfill my order. Basically, AT&T told me they sold out so they canceled my order so I can proceed to reorder again. It took them 4 days to realize this. I will be lucky if I get a new phone by Christmas. I am sure they will find a way to cancel my order again.
Again, I argued, how is this my fault. I placed my order at the store around 11 a.m. Pacific time. My friend ordered his phone online sometime after me. He got his but my order was canceled. AT&T tried to explain to me that they sold over 600,000 phones, almost 500 per minute during there peak. Again, I asked, how this was my fault.
I can understand over selling the phone. It is a great product. There is no reason to cancel my order. You adjust my order and tell me you will let me know when my phone will be in. I would have been mad that my phone was going to be late but I would have survived. At least I would be getting one.
At this point, I have no order and AT&T or Apple website will allow me to order one. I just want to get in the QUEUE for one.
Frustrated.

I have an iPhone 3GS and I want to update to iOS 4.2.1. In my settings I don't even have the ability to "update software." What should I do?

I have an iPhone 3GS. I want to update to iOS 4.2.1. In settings, general, I do not have a software update option. What to do?

You won't see this until you update to iOS 5. You'll have to update using iTunes by going to the Summary tab of your sync settings and clicking on Check for Update (you will probably be prompted that there is an update available when you connect your phone and open iTunes).

Without more information, I have to say it sounds like the phone you have was not legitimately unlocked, but had been hacked. Updating iOS will re-lock it to the original carrier.
ONLY the carrier it is locked to can authorize unlocking it.
Where did you get the phone?

HT6146 i have an iPhone 5 running IOS 6.1.4. I don't want to update to IOS 7 because I don't like it. Can I download 6.1.6 to my phone or am I now forced to move to IOS & to get this security fix?

I have an iPhone 5 running IOS 6.1.4 and I don't want to update to IOS 7 because I don't like it. Can I download the security fix 6.1.6 or am I now going to have to go with 7.0.6 for this phone?

This was my question exactly. Thanks for getting to the answer even though it's not what I wanted to hear. When I tried calling Apple earlier today to get an answer, I was unceremoniously disconnected twice while on hold for several minutes.
