The iPhone's built-in SMS application does not allow you to forward a SMS message. To do that you need a 3rd-party application, WeTool, that you can get through the Installer module. Once you've installed it, launch it, go to the "Text Log" view, select the message you want to forward, click More at the top-right corner, and finally click Forward.

The iPhone's built-in SMS application does not allow you to delete a single SMS message, you can only delete a whole conversation/chat/discussion, which is something you don't generally want. To delete an individual message install WeTool through the Installer module, and launch it. Now go to the "Text Log" view, click the Delete button on the top-left corner, click the Stop symbol on the left side of the message you want to delete, and finally click the Delete button on the right side.

There's a special key combination on the iPhone that lets you easily capture screenshots from anywhere. The feature is disabled by default though, and the setting to enable it is hidden. The easiest way to enable it is by installing Screenshot Enabled with the Installer application. Once you've installed it, the feature gets automatically activated. To capture a screen now just toggle the Mute/Silent switch while holding down the Home button. The screenshot taken is saved into the Camera Roll.

The iPhone's Mail reader allows you to read small PDFs with its built-in viewer. However, it's a bit limited, and it also requires you to e-mail the PDF via e-mail and download it from the iPhone. This might be quite problematic for large files, right?

PDFviewer is a native third-party application that comes to rescue. You can get it through the Installer app, browsing under the Community Source. To upload the PDF files you need to SSH into the iPhone (refer to this FAQ if you're a Windows user, and to this FAQ if you're a Mac user) and put the files under the private/var/root/Media/PDF/ folder. If the folder does not exist, create it (note that the folder name is case sensitive though). Finally launch PDFviewer, and it will list all documents found under that specific folder. Tap on one to read it.
