WebOS Hash Codes

Hash codes (so called because they are prefixed and suffixed with "#" 'hash' characters) are entered into the phone dialer to invoke information displays and behaviors on the phone which can not be reached through menu choices.

As of webOS 1.3.5 the hash codes can be found in the following file on the phone: /usr/palm/applications/com.palm.app.phone/app/models/DialStringParser.js

Change Settings

Safe

• ##8327633696#

This enables/disables the "Sticky Dialer" feature. The sticky dialer feature, when enabled, allows the phone app to run in the background. It is enabled by default. When it is disabled, the phone application closes when it is not the "focused" card. This means that if you open the phone app, then go to browse the net, the phone app closes.

This enables/disables "Number Masking." Number masking, when enabled, masks all incoming call numbers as to ensure total privacy for the user.

This opens a "EVDO Mode" page that controls your phone's EVDO Settings. It gives you the options to force your pre into the following options: 1xRTT only, EVDO Rev 0 only, Hybrid Rev 0, EVDO only, or Hybrid Rev A (meaning pick the best available). Hybrid Rev A is likely to get you the best speed, but if you don't have good reception in your area, you may want to choose something else to conserve battery life.
