Quick Tip: Hash Codes 32
Sun, 01 Nov 2009 11:17 am EST 
This may not be something you find yourself having to use often, but like the Palm OS phones of yore, the Palm Pre has a number of “hash codes” that you can use to access otherwise hidden data and statistics about your phone. The hash codes are entered by ‘dialing’ the code through the phone app. Here are some of the more useful ones:
##DATA# (3237): Displays your network log-in information.
##DEBUG# (33284): Displays technical data of your current cellular connection, including signal strength (lower numbers are better)
##EVDO# (3836): Displays your current cellular data settings with options for 1xRTT only, EVDO Rev 0 only, Hybrid Rev 0, EVDO only, and Hybrid Rev A. Hybrid modes will select the best available connection.
##GPS# (477): Displays your longitude and latitude, elevation, speed, and GPS accuracy.
##RTN# (786): Displays the Phone Information page, which includes your ESN, software and revision numbers, refurbished status, and more.
As always, if your phone is working fine, you should just look and not touch. These settings control how your phone connects to the rest of the world; changing something without knowing what you’re doing could end badly. For more Palm Pre hash codes of the advanced variety, check out WebOS Internals.org.

Do these codes work on european Pres? They don't seem to work for me.
No these are Sprint numbers.
The number for DATA is wrong by the way Derek.
No credit for finding these, eh?
j/k, it's cool.
Is a link to the webOS Internals page with your name on it not enough? :-P
I'm just giving you a hard time. I'm just glad it's being brought to people's attention. Some of these can be really useful, and I posted the list up 4 days after the release of the phone on the forums...but nobody really seemed to take notice! Props on the post.

P.S. thanks for un-spamming my post/ip/username. For some reason, it seemed to have flagged my pre's IP as spam!
Hey, I outright say "thanks." I saw your post back in June. Good stuff if you need it.

I can finally switch from "3G" to "EDGE" like I could on my stolen iPhone. :(
That's awesome. Thanks PreCentral.
how do you do that? And what would be the benefit? (just asking)
I'd be able to conserve battery.
like with the iphone 3GS, I switch from "3G" to "EDGE" gives me about 7 more browesing hours compaired to 3G's 5.

**Sorry...this was an accidental repost. Feel free to delete!**
is there a place that has all the information that we see explained? i would like to know what the normal range might be for some things im seeing.
Google.
For the ##EVDO# entry, be aware that on Sprint Pre's if you select "EVDO Only" or "EVDO Rev 0 only" you will not be able to receive phone calls or text messages. Not sure about making/originating calls or sending text messages from the Pre.
hahaha thanks derek. im on it :)
Nope doesn't work on my UK Pre :(
These are Sprint codes, not Palm- or Pre-specific codes. Most of them work on most Sprint devices. (Obviously, ones like ##GPS# will only work on phones with a GPS.)
The ##data# one didn't work on my Sprint Pre.
Think that is supposed to be ##3282#
Not working on O2 pre :/
One hash code that you folks had a long while ago included info about how many times the slider had been opened, minutes logged etc .... Does anyone still have that one?
Where do you enter these?
From the phone pad.
There's a video on YouTube.com that demonstrates this.

Try the following link to see how many times you've opened and closed the slider on the Pre.

Two values are given. I'm not quite sure which is the actual count as one is called the Hall sensor value, and the other is the Optical sensor value.
Anyone want to chime in??

Free beer - find out how:
I've been very tempted to try every one of these just to see what's all in there. There was a thread I saw a long time ago (I thought it was on treocentral, but can't find it now for the life of me) where they improved the reception of a phone by tweaking some of the numbers. Basically it had to do with lowering the threshold signal strength that your phone needed to hold a call or send/receive data. AS much as I love my Pre, my Q9c just rocks when it comes to picking up a signal where other phones get nothing. I know the signal is there, just the pre (and no other phone besides my Q) can pick it up.
Beer for anyone who can find that post!
Hey I'm a little confused on the elevation... is it in feet? I live in Colorado Springs, Co and I know our elevation is around 6000 ft but it says I'm only at 2030. Anyone have an idea of why this is? Thanks.
No source to cite, but I've just assumed meters for altitude &c. in that display.
#SPRINT# is one too but I cant get past the password
The code for the phone ap looks like it tries to interpret any six-digit hash code as an MSL. So ##SPRINT# is just an invalid MSL -- a password that you can't get past. 'twas a good guess to try.
