So you've been having some problems with your Pocket PC 2002?  Well Microsoft released Service Pack 4 to all the the hardware manufacturers.  It fixes multiple problems that have been reported, including some networking issues.  I have some information in the Pocket PC 2002 Software Bugs List. The Service Pack 4 actually replaces some of the flash rom programs with updated versions of program so no additional ram is required after installation.  You will need 16 MB of free ram before loading the Service Pack 4.  If you do not have this free ram, you will not be able to install it. Service Pack 3 includes all the updates from Service Pack 1, 2 and 3 so you can install Service Pack 4 instead of Service Pack 1, 2 or 3 and get all the updates.  Also there is no option to uninstall this service pack once you install it!

What's Included?

At this time, Microsoft does not provide a comprehensive list of all the files that are being updated via XIP on the Pocket PC.  By opening the .CAB file and viewing the file list, we can see that the following regions and applications are installed:

  1. Sync -

  2. Shell -

  3. Browsing -

  4. Coreapps -

For 24 MB roms:

  1. Apps -

  2. Consumer -

Windows Media Player 8.5 is installed as is the new Bliss theme however they are NOT installed in the iPAQ 3600 with the Pocket PC 2002 upgrade..  I do not know which XIP it is contained in.

See Microsoft's Pocket PC 2002 Service Pack 4 (EUU4) README for details.

Identifying if the Service Pack 4 has been Installed

Microsoft did not create a standard way to identify when Service Packs are installed on the Pocket PC 2002.  Since this service pack is so new, I have not identified a way to know if it is installed.

OEMs that offer the Service Pack 4 for the Pocket PC 2002:

The following OEMs offer Service Pack 4 for the Pocket PC 2002. Some users have installed the Microsoft Service Pack 4 from other OEMS onto their Pocket PC sucessfully.  Currently no OEM has included their own patch along with Microsoft's SP4.
