Wifi as default data connection?

[dtanPPCGeeks]

Is there a way to configure (registry or otherwise) the TP to start Wifi as the default data connection (instead of 3G) for all data-requiring apps (Skype, Skyfire, Palringo, Nimbuzz, Fb etc.)

ie. Logic flow being ...
. start app
. app will start Wifi for data connection
. if no known Wifi connection avail, then start the Wifi location list
. if no Wifi hotspots in range, then start 3G
. if no 3G, then FAIL

Thanks!
