I have found a different way of enabling SIM Toolkit on WP7 1st Gen Devices after looking thru the FieldTest registry and found that it may be similar to the registry for STK. Just to confirm, can anyone with a 2nd Gen device with STK give me the registry entries for HKEY_LOCAL_MACHINE\Software\Microsoft\SimToolkit ? Please be cooperative and help me out here.
[UPDATE 7/19/12] BETA TESTERS NEEDED!
Install the first attached XAP file, then run the app, restart your device and install the second XAP file from
here and go to settings and run "SIM Applications".
Please inform me whether this works!!
Feedback will be appreciated
Happy Development
