Is there a way to search for a number in Google while keeping the ongoing call intact? I have noticed that the internet connection is lost when a call is in progress.
I believe this depends on your provider.
For example: Verizon's CDMA network does not allow you to do Data + Call; however AT&T's GSM network will.
And as eldarerathis points out:
So this ends up being device, and carrier dependent.
