Many iphone 3G users are already hacking and jailbreaking their iphone 3G with the latest IOS4 including multitasking. As a matter fact I am one of those users.
I recently used the redsn0w 0.9.5 beta 5 to jailbreak my iphone 3G and now I’m running all the new functionality of the iphone 4 without any issues.
When I first attempted the jailbreak I experienced some major lag. I automatically assumed this was from the multitasking but to my surprise this was not the cause.
It turns out the lag was being caused by apples new wallpaper option. I don’t know why this would ever cause a lag but after re jailbreaking and removing the check box for the wallpaper I experienced no lag what so ever.
The article on how to jailbreak your iphone 3G with the multitasking and IOS4 complete functionality can be found here, Jailbreak your iphone 3G with IOS4. I will however share the details with you here today in this article.
#1. Download iOS 4 for your iPhone 3G. Place it on your desktop for easy access.
#2. Download redsn0w 0.9.5b5-4. (just Google it) It’s available for both Mac and Windows.
#3. Download and install iTunes 9.2
#4. Now connect your iPhone 3G to your computer and using iTunes, upgrade to iOS 4. Do this the official way and update your phone if not completed already.
#5. Now that you have iOS 4 final build on your iPhone 3G, you’ll have to jailbreak it by using the iOS 4 with redsn0w 0.9.5 Beta 5. Click browse and point it to iOS 4 firmware and follow the instructions on screen. Remember to enable battery percentage and multitasking. [Vista users might need to run redsn0w as administrator] Remember not to enable wallpapers.
#6. Once you’re done and the iPhone reboots, you should have a jailbroken iPhone 3G.
#7. Now go to Cydia and add the following repo http://repo666.ultrasn0w.com. Check here for how to do this. Search for ultrasn0w 0.9.3 and install it and reboot again. Your iPhone 3G is now carrier unlocked. Also remember to add this repo to Cydia http://apt.saurik.com/cydia-3.7.
The article is easy to follow and provides all the links you need in order to accomplish the jailbreak. I hope you enjoyed the article unrelated to blogging I plan on doing some more of these as we move forward.

Excellent article, and timely since I have been having a couple of niggling query’s about a jail broken iphone
Wonder if its possible to reverse engineer a jail broken iphone ? Or even likely that one may want to ?
I have always believed that jail broken iphones are prevented from receiving Firmware version updates, so if this true how can it be beneficial owning a jail broken one ?

Hi there pcd2k, you have to understand any updates that apple has the jailbreak team will release a new update for their jailbreak. So you don’t update with apple anymore you update with the development team updates.
It’s always very easy and normally a click of a button. I simply turn off any apple updates and wait for releases from the jailbreak team. Trust me your not missing much from apple.
