Requirements ?

• Hardware requirements

• Pocket PC

• Software requirements

• Wireless Internet Access ( ISP )
• Flash support
• Flash Assist software from http//www.antmobile.
  com

Why Flash Assist ?

• Pocket IE minimizes the screen size available
• Pocket IE consumes more resources and is slower
• Pocket PC needs HTML to run SWF
• After exit from Pocket IE SWF still keeps running
