Palm Pre have buried the developer mode, a mode the average person will never need behind the throwback Konami code, but why hide useful stuff ?

If you enter RocknRollHax on your keyboard (using caps) while in your email application, this will enable you to email in the landscape mode, we found this via engadget. It is thought Palm Pre hid this from the end users as they thought it was maybe too weird for your average user.

The only problem if you really want this is, you need to enter the code every time you want to use it. The plus is you will not have to root to get it. Try it out and let us know what you think and how easy it was to use.
