My speed tests of iOS 4 Gold Master VS iPhone OS 3.1.2 on 2 identical 2nd Gen. iPod Touch’s.
Overall iOS 4 is much slower on this older iPod. You may want to think twice before upgrading since you do not gain many features on older hardware.

This method has been tested and works with iPhone OS 1.14 thru 3.1.3 and on all iPhone models (2G, 3G, 3GS) not tested on iPod Touch, but should work.
HAS NOT BEEN TESTED ON ITUNES 9.2 OR Apple IOS4 (CURRENT VERSIONS)
**WARNING– Unlockers WILL LOSE carrier unlock with this method if they update to 3.1.3 or 4.0 in iTunes!**
*Try the following procedure at your own risk, you WILL lose all your data (music, photos, high scores, etc.. ) with this method but will have a working phone again. You just need to re-sync with iTunes to get your apps, songs, movies, etc.. back after your phone is fixed*

I’ve found from much trial and error that having too many iPhone “official” 3rd Apple App store apps installed when you try to jailbreak the phone may sometimes cause the phone to hang up in a state of constant reboot.
Although I can’t and don’t guarantee this will work 100% of the time, if you’ve tried to jailbreak your iPhone and your phone gets stuck at the Apple Logo and reboots every 5-10 minutes, you need to follow these steps:
Setting the iPhone to recovery mode allows you to perform firmware restore using iTunes.
1) Power off the iPhone by depressing both the sleep/wake button on the top of the iPhone and the home button. Wait for the iPhone screen to turn black aka screen-off.
2) Depress the home button and connect the iPhone/iPod sync cable into the docking port on the bottom of the iPhone at the sametime without removing pressure on the home button.
3) You should be able to see the Apple logo coming up on the iPhone and then the recovery screen with be shown after the Apple logo:

4) iTunes will start and inform you that it has detected an iPhone in recovery mode and you should restore your iPhone to start using it.
5) Perform your firmware restore.
6) Exit iTunes and Re-jailbreak. I highly recommend using Spirit jailbreak but you can use, Pwnage Tool or BlackRa1n (or whatever jailbreak tool that will work on your model iPhone). Run the jailbreak app again and everything should go fine. Spirit takes about 3 minutes to jailbreak a 3GS and about 5 minutes to complete an older model.
7) Don’t restore from a backup, just set up your phone as a new phone, then re-sync to add back all your data and apps.
DONE!
ONCE AGAIN, **Unlockers WILL LOSE carrier unlock with this method if they update to 3.1.3 or 4.0 in iTunes and I can’t guarantee this will work 100% of the time, also I am not responsible for any lost data or a bricked phone or anything other problems encountered from trying this method. Try at your own risk, leave a comment and I’ll try to help out with any issues.
New untethered jailbeak for latest iphone, ipod touch and ipad is OUT!! Go to http://spiritjb.com/ for mac and windows downloads. Works with iPhone, iPhone 3g, and iPhone 3gs, all iPod touch models and even the iPad!
Windows 7/Vista users, run in win98 compatibility mode or jailbreak will exit with an error!
As always, try at your own risk!
The app you need to buy is the LogMeIn Ignition app from here:http://itunes.apple.com/WebObjects/MZStore.woa/wa/viewSoftware?id=299616801&mt=8
Its expensive for an iPhone app at $30 but allows you to access your PC or Mac remotely from your iPhone anywhere. Download and install the app then download and install their free PC access client on your computer.
You can then log in to your home computer on your phone from anywhere as long as you have either 3G or WiFi. It works surprisingly well! Then just load up your web browser remotely on your PC and head on over to farmville.
Some tips:
The remote PC’s mouse cursor stays fixed in the center of your iphone screen, so you scroll the PC’s desktop _under_ the mouse cursor then tap on the screen to click on something– Sounds strange but once I played with it a while and got used to it I could fly though the game.

As always when a new firmware is being realeased, there is always a few unlucky people who “accidentally” update or restore to the latest firmware, thus losing their jailbreak and unlock.
In this case, you’d usually want to downgrade your iPhone from 3.1.3 to 3.1.2 simply by downloading 3.1.2 and SHIFT + Restore in iTunes so that you can choose your own firmware to restore to.
The problem is that Apple recently stopped signing all previous firmware versions making it impossible for you to downgrade.

iREB a handy utility for Windows and Mac that can solve unknown errors 21, 1604, 1601, etc.. from iTunes that are displayed during a system restore or a firmware downgrade. iREB is developed by iH8sn0w, and today he released a new update for iREB.

Computer security firm Intego has identified the first known truly malicious code which targets jailbroken iPhones with default root passwords.
The malware scans for phones on a given network with an open SSH port, then attempts to log in using the default root password that is the same on all iPhones.
Non-jailbroken iPhones are completely unaffected by this malware. Jailbroken iPhones without OpenSSH installed are not vunerable.
