Pocket PC 2002 was released and soon after Service Pack One. There was additional Service Pack Upgrades and also Active Sync Upgrades along the way - with some various other "Fix" and Patches that appeared. For many models, including mine - the Compaq iPaq 3700 Series - however, the Upgrade to Windows Mobile 2003 or Pocket PC 2003 was not made available. There were only certain other models that were able to Upgrade. There were petitions launched to manufacturers and so on - but to no avail for models left behind. This was strange and seemed rude in some way, because it instantly made you feel like you had a $500.00 state-of-the-art Mobile Computer that was suddenly a Windows 95 for no apparent reason.

Download the new ActiveSync 3.6 Version Upgrade here. I have upgraded from PocketPC 2002/ARM ActiveSync 3.5 installed to the 3.6, and it works fine and seemingly smoother and quicker.

Wakeup Tweak (Windows Mobile 2003 Alarm Fix)
Wakeup Tweak is a little program that corrects a bug that appeared in Windows Mobile 2003 concerning alarms that don't always ring when they should.
http://www.pocketpcfreewares.com/en/index.php?soft=876
Wakeup Tweak - v1.0, Mobile2003 Fix- concerning alarms that don't always ring when they should
Everyone knows now that the PocketPC turns itself on at midnight to execute some maintenance routines, in particular the alarm initialisation. There is a fault in that the delay to switch on the Pocket PC is only 15 seconds, and that that time lapse is too short to do it correctly. Consequently, some users had have the unpleasant surprise of not hearing their Pocket PC ring out when it should have. This bug can be corrected by a change to the Registry, but if you are not too inspired to do this, you can install this utility instead. It allows you to define the switched on time and the author recommends 60 seconds. Note that you can also set a complete switch on of the Pocket PC ("wake up PPC to full power mode") but that you then run the risk of starting programs that stops automatic shut down of the PPC: consider the batteries! Note : this utility is of interest to Windows Mobile 2003 users only, the other machines below Pocket PC 2002 don't have this bug.
