From the apple support site:

iOS: Forgotten passcode or device disabled after entering wrong passcode When you set up a passcode to secure the use of your iPhone, iPad, or iPod touch and then enter the wrong passcode, you may see a a message saying your device is "disabled". Learn what to do if you have forgotten or can't remember your passcode, or if your device displays a message saying it is disabled.If you enter the wrong passcode six or more times, you'll see a message that says one of the following:

• iPhone is disabled
• iPad is disabled
• iPod touch is disabled

1. Connect the device to the computer with which you normally sync and open iTunes.
   Note: If iTunes asks you to enter the passcode, try another computer that you have synced with. Otherwise, go to "If you have never synced your device with iTunes, or you do not have access to a computer" section below.
2. If the device is still disabled, or if iTunes does not automatically sync your device, sync the device with iTunes.
3. When the backup and sync is complete, restore your device.
4. When iOS Setup Assistant asks to set up your device, choose "Restore from iTunes backup".
5. Select your device in iTunes and choose the most recent backup of your device.

Hope this helps!

Hello Dass,

Press and hold down the Sleep/Wake button and Home button simultaneously for at least 10 seconds; the screen will clear out and then the Apple logo will appear on the black background. When the logo appears it means that reset is done.

If you have lost your iTunes password you can reset it here: https://iforgot.apple.com/

If you have forgotten your passcode on your iPhone you have to restore it to factory settings

iPhone setting:*
- Auto-Lock: 1 Minute;*
- Passcode Lock: On, require passcode immediately, after 15 min or 4 hours etc;*
- Network: Turn 3G Off

Scenario 1: Home screen is active with screen on*
1. Press power button for seconds until asked to '"slide to power off"
2. Slide to power off
3. press power button to turn on iPhone
4.*When asked to enter passcode, touch the "Cancel" key, then slide to unlock
5. bypassed passcode

Scenario 2:*
1. On the screen of being asked to enter passcode, press power button for seconds until asked to '"slide to power off"
2.*Slide to power off
3. press power button to turn on iPhone
4.*When asked to enter passcode, DO NOT touch any key on the screen, press power button for seconds until asked to '"slide to power off"
5. Slide to power off
6. press power button to turn on iPhone
7.*When asked to enter passcode, touch the "Cancel" key on the right bottom corner, then slide to unlock
8. bypassed passcode

Notes:
1. When Network setting changes to Enable 3G: ON, "3G" signal shows up, passcode CANNOT be passed through
Go to a underground parking lot or a lift where 3G signal is weak, when 3G signal switches to "E" (Edge), passcode CAN be passed through following above steps
2. When no 3G or Edge signal, above steps don't work

Conclusion:
Seems passcode security is related to network status
Possible security hole under Edge
