Develop WM Smathphone/Pocket PC App for T-Mobile Dash

Setup Device:

• Download regEditSTG to edit policy on Dash, HKLM\Security\Policies\Policies\ 00001001 =1 00001005 =40 (from 16)
  
• Download SDA_ApplicationUnlock and run
  
• run C:\Program Files\Windows Mobile 5.0 SDK R2\Tools\SdkCerts.cab, RapiConfig
