Looking to customize your iPhone?

So its been 2 months and you are itching to begin installing other free open source software that apple doesn't provide, but haven't gotten around to it yet? Now is the time! Since the iPhone came out, many busy little hackers have been pushing out several killer applications for the iPhone, and hacking your iPhone to install those apps has become nearly effortless.

Adam Pash from Lifehacker has written a concise step-by-step set of instructions on how to hack your iPhone and install 3rd party software (which he so graciously added a few links to some of those softwares for our convenience).

If maybe you want to try for a more serious (and potentially dangerous to your phone) hack, like getting the iPhone to work with other GSM providers, then I suggest you take a look at George's Blog on how he managed to hack the iPhone. If you remember, George is a 17 year old college student who, with a group of hackers, was among the first to hack the iPhone and make it available on other providers. He has since traded that iPhone for a Nissan 350Z and 3 other iPhones to the founder of Certicell. He has written a few updates that make this hack just a little more simple and less likely to brick your iPhone.

Disable users on XP's Welcome Screen

When you add an account for certain users with Windows XP, their user names will appear on the Welcome Screen.

Sometimes a user needs to be added to a Windows XP machine, because he needs access (via the network or remote login) to resources on the machine, but he will not be physically logging in on the computer. You can remove his name from the Welcome Screen, while still maintaining the user account with the Registry editor.

WARNING!: Changes made to the Windows registry happen immediately, and no backup is automatically made. Do not edit the Windows registry unless you are confident about doing so.

Microsoft has issued the following warning with respect to the Registry Editor:

"Using Registry Editor incorrectly can cause serious, system-wide problems that may require you to re-install Windows to correct them. Microsoft cannot guarantee that any problems resulting from the use of Registry Editor can be solved. Use this tool at your own risk."

Edit at your own risk!

Start the Registry Editor

Go to

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT \CurrentVersion\Winlogon\SpecialAccounts\UserList\

Right-click an empty space in the right pane and select New > DWORD Value

Name the new value exactly as the Username

Leave the Value data as 0

If you want to enable this user again on the Welcome Screen, either double-click the Username value and change the Value data to 1, or delete the Username

And there you have it! A user that can log on remotely, but is not on the Welcome Screen.
