How to speedup your slow iPhone 3G… downgrade your OS dum dum!
This post is for people who own an “old school” iPhone 3G and want it to be fast again.
Feel free to skip the intro.
Remember when you first got your iPhone 3G? Remember how state-of-the-art it was? Remember loading maps and walking through the West Village (or any other wacky neighborhood) navigating it like a genius? Remember being able to take a whole series of photos at the speed of a paparazzi? Do you remember?
Well, if you’ve followed all of the iOS upgrades and now find yourself on iOS 4—most likely iOS 4.2.1—then your iPhone 3G most likely sucks. It will freeze when you’re lost and need directions. It will freeze when you want to make an important phone call. It will freeze when you’re trying to snap photos of an assailant. You’ve been robbed of the tasks which once made you an invincible smart-phone superhero (except having good phone service, you never had that…)
If you want to taste that sweet nectar of a new iPhone once more without having to actually buy a new iPhone, then I have the solution for you…
Downgrade your iPhone 3G from iOS 4 to iOS 3.1.3
It turns out that the newer operating system makes the iPhone 3G utterly unusable, but it’s easy to fix this problem. Here’s a full tutorial from iphonehacks.com on how to do the downgrade. It boils down to:
- backup/sync your phone
- download iOS 3.1.3 & RecBoot
- set your iPhone to DFU mode
- restore your phone with the iOS 3.1.3 software
- exit recovery mode using RecBoot
- restore from a pre iOS 4 backup and sync
After that you should have all your contacts and most of your apps back, but not photos, old texts, starred phone numbers—you should download your photos ahead of time with iPhoto, ImageCapture, or whatever. More importantly you’ll have a phone that is quick again. It’s probably the best thing you could do with an iPhone 3G.
Get out of Jail Free: now that you’re running iOS 3.1.3, if you want to jailbreak your phone, you can easily do that by going to jailbreakme.com on your iphone and using their one-click jailbreak. Unfortunately unlocking your phone is a lot harder and maybe requires changing the OS again? (Basically the latest modem firmware 05.15.04 was a no-go when this post was written, and the only exploit requires upgrading it to an ipad 06.15.00)
Just to reiterate… downgrade your iPhone 3G iOS 4.2.1 to iOS 3.1.3 it will positively affect your life. Buy a new phone when you’re ready, if you’ve waited this long, wait for the iPhone 5 or just get a different phone…
