Although you may not use these often they may come in handy at some stage as the guys over at precentral have come up with several Palm Pre hash codes which can apparently access hidden statistics and data.

The guys gained the info via webos-internals, who have quite a list of Palm Pre hash codes available, and hash codes are entered by dialling the code via the phone application.

So here’s a few to go on with…##DEBUG# (33284) this displays tech data of your current mobile connection and includes signal strength…##DATA# (3237) shows network log-in info…##GPS# (447) shows latitude and longitude, speed, elevation and GSP accuracy…##RTN# (786) shows the handset info page with ESN, revision numbers, refurbish status and software…##EVDO# (3836) shows current data settings along with potions for 1xRRT only, Hybrid Rev.0, EVDO Rev 0 only, EVDO only, and Hybrid Rev A.

Of course changing any of the above without knowing what you are doing could cause problems so proceed with caution.
