1 - How to unlock: Go to the Unlocking section. Two options, AnySIM or iUnlock.
2 - How to avoid non-caller ID appearing on your iPhone (you dont have to edit your entire contact database). Go
here.3 - How to restore your iPhone when your iPhone freezes after installing non-supported 3rd party applications. My own personal advice? Download all the available firmware images files in .ipsw format , so that you have the choice of restoring to a particular firmware when needed to. Press ALT in iTunes when initiating a restore to choose which firmware file to restore to.
4 - How to customise your iPhone , currently two solutions, they are Summerboard and Customise, both apps can be downloaded via Installer.app, iFuntastic on Mac or iBrickr on WinXP. Personal preference? Summerboard. Themes are downloadable via Installer.app on your iPhone.
5 - How to unlock a 1.1.1 to a working 1.0.2 iPhone MINUS the phone functions. Go

6 - How to sync songs, photos and contacts to your iPhone. This can easily be referred to the downloadable iPhone User Guide in PDF form, at www.apple.com/iphone
7 - How to set the voicemail button on the Phone tab to your current voicemail shortcut key.
8 - How to re-enable your Youtube once you have gone through the entire unlocking process. The unlocking process either patches or rewrtie the baseband file, which disables, among other things, the Youtube on your iPhone. To re-enable this, search for an application called PACAY, it's a single batch file that does the re-enabling in a single click, doesnt get any easier for virgin unlockers out there. Go
here.9 - How to break the 8Gb barrier for storage content ? Stream it! Use TVersity for PC, or EyeTV for Mac, or if you are looking for other MP3s, use Seeqpod.com. Type www.seeqpod.com on your Safari, and stream it!
