I dropped my iphone 2g 16GB in a toilet bowl last month. I managed to dry it out but currently having problems in restoring it. ITunes just keep giving me errors like 1611, 1604, 23 and so on. I tried to switch on the iphone but it didn't give any response. When I plugged it into my computer, it only shows the connect to ITunes icon. Does anybody have a solution to this problem?

Just follow this easy tutorial: How to Factory Reset iPhone Any Generation clean slate can do wonders in...

Your iPhone enables you to add a four-digit passcode which locks your phone to prevent unauthorized users from using your cell phone.
When you enable the passcode, your iPhone prompts you to enter the four-digit code before you can unlock your phone.
However, if you have forgotten the passcode and unable to use your iPhone, you can override the passcode using iTunes the default iPhone management program.

Restore your iPhone back to the default settings to override the passcode.
To do so, connect your iPhone to the computer using the USB cable that came with your phone and launch iTunes.
iTunes displays your device in the left panel under "Devices."
Click your iPhone under "Devices" and click the "Summary" tab.
Click the "Restore" button.
Keeping in mind that restoring your iPhone back to the default settings deletes all the currently saved information.
When prompted, click "Backup" to back up your iPhone.
Click "Restore" again and follow the final guided prompts to restore your iPhone back to the default settings.
When the process completes, click "OK." You should see the "Connect to iTunes" message on your phone.
Keep your iPhone connected to the computer until the "Connect to iTunes" screen goes away or you see "iPhone is activated" message on your phone.
Right-click your iPhone under "Devices" and click "Eject."
Close iTunes and disconnect your iPhone from the computer.
Your iPhone no longer prompts you to enter the passcode.

Take off back cover , remove battery and blow with hair dryer.

You need a full system restore, plug into itunes and click restore, apple will guide you through the rest. This will delete all data but it will sync it back to the last time that you synced your iphone.

Hi,
Here u can follow the steps

Step 1: Make sure you have downloaded the latest version of iTunes if you haven’t already. Download iTunes 8.2 from the link given below.
Step 2: Now connect your iPhone with your PC. You must connect it to a single usb port on the backside of your computer. Do not use any usb hub or the ports in the front as this could cause an error during update process.
Step 3: Start iTunes 8.2. Sync your iPhone with your PC so that iTunes backs-up all your important data including settings, apps, music, contacts and photos.
Step 4: You will now have to download a custom cooked firmware for your iPhone version (2G or 3G). I can’t post the download links for these files for the reasons you all know very well. Just Google “iPhone 2G Custom 3.0” (If you are using iPhone 2G) or “iPhone 3G Custom 3.0” (If you are using iPhone 3G) and use one of the torrent links to download the custom created .ipsw file.
Step 5: Once you have downloaded the required .ipsw file, Copy/Paste it into this location:
“C:\Users\[username]\AppData\Roaming\Apple Computer\iTunes\iPhone Software Updates\” (Windows 7)
“C:\Users\[username]\AppData\Roaming\Apple Computer\iTunes\iPhone Software Updates\” (Windows Vista)
“C:\Documents and Settings\[username]\Application Data\Apple Computer\iTunes\iPhone Software Update\” (Windows XP)
Step 6: Restart iTunes. You will now be prompted to install this firmware you just download. Just close this prompt dialog by clicking on “x” from the top right-most corner of the window.

Step 7: Now you will have to restore your iPhone to this custom firmware 3.0 that you just downloaded. Click on your phone from the sidebar in iTunes to get to this screen as shown in the screenshot below:

Now press and hold left “Shift” button on the keyboard and then click on “Restore” (Not “Update) button in the iTunes and then release the “Shift” button.

This will make iTunes prompt you to select the location for your downloaded custom firmware 3.0. Select the downloaded .ipsw file and click on “Open”.
Step 8: Now sit back and enjoy as iTunes does the rest for you. This will involve a series of automated steps some of which are highlighted below:

Don’t do anything silly at this point. Just wait while iTunes installs the new firmware 3.0 on your iPhone. Your iPhone screen at this point will be showing a progress bar indicating installation progress. After the installation is done, iPhone will restart automatically and you should now have a fully unlocked and jailbroken iPhone 2G. iPhone 3G on the hand will only be jailbroken, not unlocked. iPhone 3G users will have to wait for Dev-Team to release ultrasn0w on Cydia in order to unlock their phones.
Step 9: Once you are done with the unlocking and jailbreak process. You can now restore all your settings, apps, music, contacts and photos to the newly installed firmware version 3.0 by restoring the backup that you made in Step 3 from iTunes.

Feel free to ask me any question here should you run into any problem during the update process.

The only way to unlock any ipod with out the password is to restore it using itunes. In case you are unfamiliar with how to do a restore on your ipod touch i have posted a step by step below. Take care :)

Last Modified: February 16, 2009 Article: HT1414 Old Article: 305744 Using the Restore function for your iPhone or iPod touch is part of standard troubleshooting procedure. Restoring your device will erase all data from your iPhone or iPod touch, including songs, videos, contacts, photos, calendar information, and any other data. All iPhone or iPod touch settings are restored to their factory condition.
Whenever you restore your iPhone or iPod touch, Apple highly recommends that you perform a sync prior to restoring in order to back up any changes since your last sync. If you have movie rentals on the device, see this document before restoring.
Use the following steps to restore your iPhone or iPod touch:
Make sure you have the latest version of iTunes installed and running before attempting to update. Connect your iPhone or iPod touch to your computer. Select your iPhone or iPod touch when it appears in iTunes under Devices. Select the Summary tab. Select the Restore option. When prompted to back up your iPhone or iPod touch's settings before restoring, select the Back Up option (as seen in the image below). If have just backed up the device, it is not necessary to create another.
Select the Restore option when iTunes prompts you (As long as you've backed up your device, you should not have to worry about restoring your phone).
Once the restore process has completed the iPhone or iPod touch restarts and displays the Apple logo while starting up
