This is a small collection of tips for different machines...
Please note:

• Some of these tips CAN CAUSE SERIOUS PROBLEMS if done incorrectly!
  If you're not certain about something, DON'T DO IT!
• Please note that some EPOC tips are for the ER3 machines (Psion s5 'Classic' and the Geofox One) only. Trying them on a newer machine WILL cause problems!
• I take NO RESPONSIBILITY if anything goes wrong!
