Post registry and software hacks to make your TyTN do even more here.

(Obviously none of these will be supported by either HTC or your local phone service provider. Use these at your own risk.)

Registry Editors:
Mobile Registry Editor
Works with Mobile 5 though developed for older

Change Bluetooth Name Without Changing Owner Name

Normally the name of your device which is displayed when using bluetooth is the owner name.
To change this use a registry editor and browse to
\HCKU\Software\Microsoft\Bluetooth\Settings\Local Name
And change the value of the local name key to what ever you want.

Internet Explorer Navigation

The default behaviour for your device's four-way direction button in Pocket Internet Explorer (PIE) is to jump between hyperlinks/form fields on a web page. To change this behaviour so that the button scrolls the page left, right, up and down, use the following tweak:

\HKLM\Software\Microsoft\Internet Explorer\Navigation\4-Way Nav = 0 (DWORD decimal)
And to re-enable hyperlink/form field navigation:
\HKLM\Software\Microsoft\Internet Explorer\Navigation\4-Way Nav = 1 (DWORD decimal)
NB: You may still jump between links using Tab and Shift-Tab if your device has a built-in hardware keyboard.

WM5: Increase Performance and Speed

Boost Windows Mobile 5 performance by makeing the following changes in the registry...

[HKLM\System\StorageManager\FATFS] CacheSize = 4096 EnableCache = 1

[HKLM\System\StorageManager\Filters\fsreplxfilt] ReplStoreCacheSize = 4096
Default values for all keys are 0. Soft reset for changes to take effect.

Disable Menu Animation

Navigate to HKEY_LOCAL_MACHINE\SYSTEM\GWE\Menu, then change the value of "AniType" from 6 (default) to 0.
This disables the menu animation which helps in speeding up your PocketPC.

Change the Tap and Hold Dots Colours

1) Go to the HKLM\SOFTWARE\Microsoft\Color\ key.
2) Add a Binary value called "40" if it does not already exist.
3) Set the value to "rr gg bb 00" (RGB hex values 00 to FF so "FF 00 000 00" is Red)

SMS Settings

SMS Notification Always On
"SMSDeliveryNotify"=dword:00000001 ->0 to disable, 1 to enable.

Disable SMS Sent Notification
"SMSNoSentMsg"=dword:00000001 ->0 to enable, 1 to disable.

Bottom tray icons

Remove the Battery Icon:

Remove the Wireless Manager Icon:

Restore local language support for sliding keyboard after upgrade to a different language ROM

This has been reported not to work, see below for another hack
You need to create Registry value of name "Locale" and type of "String" and data of "Localization ID" within [HKEY_CURRENT_USER\ControlPanel\Keybd]

Localization IDs:
French = 040c
German = 0407
Italian = 0410
Japanese = 0411
Kazakh = 043f
Russian = 0419

Other IDs can be found here: Tweaks and Hacks - htcwiki

Some versions of the OS seem to be case sensitive on this value, and if it does not work, try upper case letters. Registry example for say russian kbd:


Modification to keyboard hack. The above solution does not work for the Hermes the following new settings are required.

Goto the following registry entry


There is a key called 'Layout' and it is in Decimal.

The default value of English ROM is 20409, and Chinese ROM is 20404 (both are in hexadecimal).

The suitable value for German Hermes keyboard is 20407 (132103 in decimal).
Probably Hermes use 20+country ID (409=WWE, 407=German, 404=Trad. Chinese, etc...) format for keyboard layout value.

The above settings does not work with the latest Hermes firmware, the following is required.

[HKEY_CURRENT_USER\keyboard layout\Preload]
[HKEY_CURRENT_USER\keyboard layout\Preload\1]


The last setting is the same as in the above solution
These settings are for Norwegian keyboard, country code : 0414

Tested on fw. 1.31.502.1

Improve BT A2DP sound quality

Add new dword, Value name=BitPool; Value data=48 (Decimal)
Modify, Value name=UseJointStereo; Value data=0 (Decimal, Originally 1)

For BitPool:
Microsoft suggests the following bitpool values for optimal buffer sizes.
30 - Low audio quality
40 - Medium audio quality
48 - High audio quality
58 - Excellent audio quality
Chose one you like. I think 48 is good enough.

For UseJointStereo: use 0 instead of 1, then you got the real stereo.

Show Network Operator Name in today screen

Restoring Today Item: WiFi, BT and Phone Connection Status

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Today\Items] Create "Wireless" use Key "Flags"=dword:00000000
  • Enable clicking on the today plugin above open Comm Manager
[HKEY_LOCAL_MACHINE\ControlPanel\WrlsMgr] Create key "Redirect" "Redirect"= "\Windows\CommManager.exe"

Restore clock on top bar

"ShowTitleBarClock"=1 (enable)
"ShowTitleBarClock"=0 (disable)

PocketIE Cache in storage card

Create these folders:

\Storage Card\Pocket IE\Temporary Internet Files
\Storage Card\Pocket IE\Cookies
\Storage Card\Pocket IE\History

Add the following registry keys, string data type:

[HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders]
"Cache"="\Storage Card\Pocket IE\Temporary Internet Files"
"Cookies"="\Storage Card\Pocket IE\Cookies"
"History"="\Storage Card\Pocket IE\History"

Disable flashing service LEDs

"Index"=0 Note! Disables vibrating.

Adding disconnect GPRS/UMTS button

To add Disconnect button and a timer display showing how long GRPS is in use for the session: HKLM\ControlPanel\Phone\Flags2 = 16 (DWORD decimal) To have only Disconnect button: HKLM\ControlPanel\Phone\Flags2 = 8 (DWORD decimal) To disable both the Disconnect button and the timer: HKLM\ControlPanel\Phone\Flags2 = 0 (DWORD decimal)

Disable annoying beeps when changing in-call volume

There are actually 3 different sounds in play here: the one at the bottom end of the slider (quietest), the one in the middle posisitions (standard), and the one at the top end of the slider (loudest). These are handled by 3 registry keys: HKCU\ControlPanel\Sounds\LoudestInCallVolume
HKCU\ControlPanel\Sounds\StandardInCallVolume Within each of these keys the default 'Script' value is 'p' for 'play', change the 'Script' value to blank (erase the 'p').

Change ringtone/vibrate/LED flash characteristics

If you would like more control over how your device rings/vibrates/flashes its LEDs on events, you can can change the Script values of these events.

For example, for an incoming call performing 'activate device, play ringtone, wait 3 seconds, repeat':

HKCU\ControlPanel\Sounds\RingTone0\Script = "apw3r" (REG_SZ string, no quotes)

For performing 'active device, set volume to 33%, play ringtone, set volume to 67%, play ringtone, set volume to 100%, play ringtone (no repeat)':

HKCU\ControlPanel\Sounds\RingTone0\Script = "ac33pc67pc100p" (REG_SZ string, no quotes)

The following are the full codes available to you.

Please note that all the codes are executed simultaneously except after a ringtone play / wait code. E.g. 'v1p' will vibrate and play at the same time, while vibrating for 1 second. But 'pv1' will play the ringtone through all the way first, then start vibrating for 1 second. a = activate device

cN = set volume to N in percentage max volume
fN = flash notification LED for N seconds
p = play ringtone. Note that this will play the ringtone all the way through before continuing with the next code.
r = repeat. Note that this should be the last code in your Script string, if used at all. The repeat will be from the most recent a. So: v3apr will vibrate once then repeat the ring signal.
vN = vibrate for N seconds
wN = wait for N seconds. Note that the device will wait this long before continuing with the next code.
