Hi Mária, I only downgraded my iPhone 4 once and that was after I optained a beta copy of iOS 5 back last year in July. I was pretty excited about iOS 5 after the June announcement so I paid some guy on eBay 5 Dollars to register my UDID under his developer account. I then had to find a website to download the iOS 5 beta, but since it was only the first or second Beta it gave me so many problems that after a week or 2 I downloaded iOS 4.3 again from the same website. Basically, as long as Apple allows downgrading and provided you find a full copy of iOS 5.1.1 which will be somewhere in the neighbourhood of 700 or 800 Megabytes to ddownload, you just download it, then if you want to downgrade you hook your phone up to iTunes and instead of pressing Enter on "Restore" you press Shift+Enter. If you are using Windows this will open a standard Open File dialogue, you then browse to where you saved the iOS 5.1.1 file which has a .ipsw extention, select it and press "Open". From then on it's a standard restore procedure and if all goes well you will be back to 5.1.1 when it's done.
Now, having said this, I don't think you have too much to worry about. iOS 6 seems to run very well on the iPhone 4 and in fact quite a few people here have reported it seems to be more responsive than iOS 5.1.1 was although there are a few exceptions where some people seem to have problems. As for features all works well except custom labels has a bug and there are a few other things which maybe you read about if you followed the list. Nothing I think is a deal breaker. If you do upgrade make sure you are plugged into power and back up before and even though some claim it makes no difference, do this after you backed up and before starting the update: Turn on Airplane Mode, then go into WiFi and turn WiFi back on still with Airplane mode enabled. This will turn off Bluetooth and the phone so at least your upgrade won't be interrupted by a phone call. Next, go to the app switcher and force quit all apps. Last, turn your iPhone off and turn it back on, basically this reboots the device. I would also plug it into a power outlet with the wall charger and not the computer, somebody mentioned yesterday that if you plug it into the computer you use to sync and have iTunes open it can cause the phone to go into DFU mode which you do not want to happen. Now you can go to "Settings", "General" and "Software Update" and start the update. Keep in mind that the download itself can take about half an hour or more and if it seems to be stuck at 96% don't panic and just let it sit, it will finish eventually. Also, the actual install with all reboots and so on can take another 30 minutes or even up to an hour, so unless Voiceover doesn't come on for about 2 hours, don't worry. If it doesn't come on after 2 hours or more, well, then do worry *smile*. I started the update via WiFi but got impatient when nothing happened for 5 minutes as it sat at 96% and I rebooted the phone. After that it kept telling me that my version 5.1.1 was the latest update so I just hooked it up to iTunes and did the update via iTunes. From all I heard from those who did the update on the phone via WiFi I think I preferred to do it via iTunes as I could always see what was happening, I heard the various sounds the computer made when the iPhone disconnected and reconnected during the update etc. If you want to do this via iTunes you have to be upgraded to the latest version which is 10.7.
