If you read that title and were overly excited, take a deep breath. Here's the details on how to hide applications from the Windows Phone 7 start menu, but keep in mind they are a tad lengthy and annoying for the time being.

Basically, this method involves removing the application title from the manifest. If the title is blank, the system will not display the application (or icon) in the applications list. This is useful if you use, say, Folders, which can launch the application without it being visible in the application list.

To do this on a homebrew application, you can do it manually, or:

• Use the XAP Manifest Tool to open the XAP
• Find the line with Author, Publisher, Genre, etc in it, and set Title="APPNAMEHERE" to Title=""
• Press Deploy, or save it and deploy manually

To do this on a Marketplace application, you will need the original XAP. Phone7Market on XDA will get you free applications. Downloading non-free applications essentially enables piracy, so you're on your own there. The video above explains how to do the following:

• Download/obtain the Marketplace application's XAP
• Open it in the XAP Manifest Tool
• Find the line with Author, Publisher, Genre, etc in it, and set Title="APPNAMEHERE" to Title=""
• Press Patch + Deploy, or press Patch and deploy the XAP manually.

It's quirky and complicated, but if you're looking to hide some rarely used homebrew tools/etc from your application list, this may proof useful. Any thoughts/tips, be sure to let us know in the comments.
