For hanging/Jam problem, few factors can be involved,
First of all you have to check, how much space is being left in phone memory after installing particular applications, To check the settings, Go to settings, Memory,
1. Soft Reset,
Try resetting the device while hold down the End Key for few seconds, when the phone is switched off take off battery for few minutes, then try putting the battery again, It will clear the memory used by the softwares,
Make sure to close all running applications before performing a soft reset, since a soft reset erases all unsaved data in such applications.
2. Hard Reset
Hard reset will restore your Ipaq to factory default settings,
Perform a factory or hard reset when there is a need to clear all settings, programs, and data from the RAM.
The applications and data present on your iPAQ before performing the hard reset can be reinstalled by synchronizing your iPAQ with a computer using ActiveSync/WMDC (Windows Mobile Device Center).
Turn off your iPAQ by holding down the End key.
Then hold down the center of the 4-Way Navigation key and turn on the iPAQ again while continuing to do so
3. A confirmation screen opens asking whether you want to perform a hard reset or not. SelectYes . The iPAQ will reboot with its original factory settings.
