1. Set an alpha-numeric passcode

By default, anyone can simply turn on your iPhone or iPod touch and access any application that you have installed. You can go to Settings -> Password -> Passcode Lock and set a 4 digit password to prevent that from happening. For stronger security I recommend that you use a password with letters, numbers, and symbols (alpha-numeric).
Here are the steps to enable an alpha-numeric password:
- 1. Go to http://www.iphoneos3.com/secure on your iPhone or iPod touch and click on the download link to download the configuration file.
- 2. Click Install button, and then click the Install Now button to install the Profile.
- 3. Once the Profile is installed you can set your password and confirm it.
2. Turn on the trusty Erase Data feature

After you’ve set your passcode, go to Settings -> Password -> Passcode Lock and switch the Erase Data slider to ON. With the Erase Data feature, all of the data on your iPhone or iPod touch will be deleted immediately after 10 unsuccessful login attempts. You should also go to Settings -> General and set the Auto-Lock time to 1 Minute so your device automatically locks after a minute of inactivity.

3. Use Find My iPhone and Remote Wipe

Apple has a service called Find My iPhone and Remote Wipe for MobileMe users. With Find My iPhone you can track the exact location of your iPhone if you lost it or if someone stole it. You can also send a message to your iPhone asking whoever finds it to return it to you. With the Remote Wipe feature you can remotely delete your Addresses, phone numbers, emails, and photos. It costs $99/year to be a MobileMe user. You can find out more about MobileMe at http://www.apple.com/mobileme.
4. Enable the anti-phishing feature for Safari

Phishing websites are basically websites or links you visit that are disguised as other sites and steal your login information. Safari has a built-in feature that automatically detects and warns you if you are visiting a phishing website. You can go to Settings -> General -> Safari to turn it on. In my tests Safari was able to detect every phishing link, but you shouldn’t just rely on Safari. When in doubt, just type in the URL of the website you want to go to instead of clicking on a link that you suspect goes to a phising website.
5. Clear your history, cache, and cookies

Some websites keep you logged in unless you log out yourself. You should clear your history, cache, and cookies after viewing websites where you are required to enter in important information like your web mail account or credit card number. To do this, go to Settings -> General – > Safari.
6. Only use secure WiFi networks

If you use WiFi , you should only stick to trusted WiFi networks that have encrypted connections.
7. Stay updated with the most current firmware

Keep your iPhone or iPod touch up to date with the latest iPhone OS firmware so that your device is not vulnerable to any exploits in older firmwares. iTunes automatically checks for updates when you sync your device.
If you have any other tips, feel free to share them with us in the comments below!

iOS4 Jailbreak for iPhone, iPod touch, and iPhone 4G
Yeah you wouldn’t want your firmware to be vulnerable to those awful exploits… You know the ones that don’t force you to stay locked to a specific carrier!!! =P
Seriously chuck ur retarded, the firmware update disables exploits such as the SMS exploit for firmware 3.0, u know the one that could zombie hour iPhone, or steal data when the bug was planted in your iPhone…seriously apple will be trying to keep the unlock ability to a low because they have a legitimate legal binding contract with AT&T, btw why are u using the gayest cell provider out there, tmobile has nothing on AT&T if I were u I would be using AT&T anyways…so what if it cost $20 more a month then tmobile, way better service, an customer service has been great…
AT&T Sucks ass!! The only thing keeping At&t alive is the Iphone other than they they would drown!!!
How can I remove the ’secure’ password lock? I like it, but the compulsory inclusion of both letters and digits is annoying me!
Go to Settings -> General -> Passcode lock and tap on the Turn Passcode Off button.
That Doesn’t Work, I Relly Want To Put It Back To The Old PassWordThing With The 4-Digits.
go to general profiles then remove profile
then disable and reenable pass code
bang its gone
Settings->General->Profile->Remove
:d

I just unlocked my iphone, but I am not able to install the applications that are on my itunes library. it keeps on giving an error. what can I do please email me
thank you
be careful when upgrading to 3.1.3 because there is no jailbreak for that firmware yet. So if you screw up your iphone and by accidentally update to that firmware you will lose your jailbreak and unlock and will be stuck with a stock iphone until someone comes out with an updated jailbreak/unlock software. check with quickpwn.com or blackra1n.com for the latest jailbreak firmware.
Please dont delete this post. I’m not advertising. Just trying to help.
Cheers
hi my iphone 3gs 3.1.2 unlocked with blackrain.can i update software to 3.1.3 from itunes.is there any problem or will lock etc…
thanx for the reply in advance
No do not upgrade in you want to keep your unlock. Mine was unlocked with blackrain and I accidently updated to 3.1.3 and now can’t unlock my itouch again and my home button doesn’t work, that is why I unlocked it to begin with so that I could put an app close from Cydia on it. Apple wants $199 to fix the home button. So wait until there is a jailbreak for 3.1.3 before you update.
if you update to 3.1.3 and you unlocked using blackra1n it will lock again
do not update if you dont want to get locked again. There is no unlock for 3.1.3 as yet
to clear the password all you have to do is resore thats the big problem
i jailbreak it sucesfully and i download from cydia snow and iphone went to recovery mode. when i try restore and it upgrading to 3.1.3 so i cancel it any help please
connect your iphone to computer and run blackra1n . do not update at all
use blackra1n after connecting your phone to pc
hi..how can i jailbreak my ipod touch 3gen version 3.1.2 model MC..i tried blackra1n it worked but i uninstalled it and i want it back on my device so i can get cydia…..can anyone help me..please..??
does i phone have sure type keyboard
is there an jailbreak for 3.1.3 yet?
For 3gs on latest bootrom no jailbreak no unlock
but for 3g 3.1.3 you can use snowbreeze
there is no jailbreak for 3.1.3 and there will not be the dev team is waiting for 4.0 to come out to jailbreak that (which is coming out in september 2010). The only difference between 3.1.3 and 3.1.2 is a very rare battery problem with 3g ipod touch on 3.1.3 and it isnt jailbreakable.
For 3gs I agree with you ,
buy for 3g 3.1.3 old bootrom snowbreeze can be used and I have used it .
Even on 3gs if you are on old bootrom (which is very rare and is only on NON MC models) it is possible to jailbreak with snowbreeze
just keep checking qwickpwn.com or redsn0w.com or blackra1n.com
Hi all,
