This page wants to be a complete list of all HTC Pocket PC tools developed by, for or near XDA-developers. It's not yet complete though, so please search the forum also if you're looking for something.
Executable for PocketPC which removes the SIMlock from Wallaby phones, provided the phone is running a PPC 2002 (not WM2003) Operating System that is newer than version 3.16.43.
Executable for Windows 2000 or XP, which extracts the unlock code from your phone over USB.
BandSwitchTool, for Siemens SX56, tool to switch between european and US gsm bands.
XDAtools: saving your ROM, flashing a new one, using ActiveSync or SD-card
Collection of OSImageTool, ?FixBootloader and adaptROM, usually combined with 'Programme A' to make a complete solution for moving ROM images between Wallaby phones, bootloader SD-cards and hard disk.
A specially made Wallaby ROM image, now somewhat older (based on the Qtek 3.16.52 ROM), which includes a lot of freeware tools and programs. Still the weapon of choice for unlocking a Wallaby with a ROM which will not run XDAunlock.
