Apple IOS4 is not for the iPhone 3G

As with the rest of the ‘sheep’ I was keen to get the new Apple IOS4 installed on myApple iPhone4 phone as soon as it came out on Monday this week. It took almost 3 hours for the whole process to complete on my iPhone 3G but never the less I plodded on. At the end of it the handset looked much more polished in the interface and seemed to be quite smooth, but alas the ‘shine’ was soon to fade <sigh>.

But the end of Tuesday the handset had become very unresponsive. For example when you pressed the ‘Power’ button or the ‘Home’ button to wake it up, it would sometimes take 2-3 seconds for it to actually switch on. Also, when calls were coming in the screen would come on for a good 2 seconds before it would display the callers name or even start to ring. All of this was far too much when you use the phone as much as I do each day so I had to find a way to downgrade again.

After a little searching I found a process that claimed that it would to do the job and it did after I did it wrong a couple of time. This is what worked for me:

  • Connect the iPhone to iTunes
  • Put the phone into DFU mode
  • Download Apple IOS3.1.3 or 3.1.2 (you can find this on a number of sites)
  • In iTunes, hold {Option} and click Restore and point to the IOS file downloaded
  • Allow it to restore. At the end it will error, this is normal
  • Now use RecBoot to exit recovery mode (I had to use a Mac for this to work)
  • Wait for your iPhone to boot up normally

A full video showing how to do this can be found here. This is not meant to be a ‘step by step’ guide on how to do as there are lots out there it is meant to be a brief guide. The information here is provided AS-IS.

Hopefully this will help others out there who are suffering with desparatly slow iPhone 3G handsets after the upgrade.

For those of you who would like to upgrade to the iPhone 4 but do not like the ridiculous handset prices from O2 et al then take a look at Tesco Mobile here as they have one of the best prices I have seen and if you didn’t know they use O2’s network anyway!!
