Welcome to the WebOS Internals wiki This site is for collecting information about the inner workings of webOS, which powers everybody (else)'s favorite smart phone, the Palm Pre. If you add information which you did not discover yourself, please try to give credit to the original researcher. Also, please do not add information that has not been confirmed. This is meant to be a collection of facts, and our site is growing quickly, so organization may sometimes be lacking.

WebOS Internals Development Kit

Palm's binary sdk the "Plugin Developer Kit" will not be available until an unnannounced future time. In the mean time, WebOS Internals has released a full "WIDK" for you using Scratchbox2. We strongly urge the community to standardize on this WIDK until Palm releases theirs. Scratchbox 2 is a cross-compilation engine, it can be used to create a highly flexible SDK. As installed below, the install process uses a script which extracts the required Palm provided files from a copy of webos doctor, and downloads from other sources, and builds a complete compilation environment automatically which can compile SDL and openGLES apps for webOS.

Enacting any set of instructions from this site has the (remote, but greater than zero) potential to void your warranty. Our intention and the specific design of all instructions is such that you should be able to recover using the webOS Doctor should anything go wrong, and put your Pre back to a state which is indistinguishable from a factory-new Pre, but we give no guarantee. Use any information from this site at your own risk. At the very least, you should be prepared to lose all data on your phone at any time. We cannot tell you what you should do - we provide the information, but it's up to your own sense of personal responsibility to determine what you do with that information. We require you to use the webOS Doctor to put your Pre back to factory condition before contacting Palm or your cellular carrier for service or support.

Note: The section called "Accessing Linux" used to be known as "Rooting your Pre".
See Accessing Linux != "rooting your Pre" for more details.
