I'm planning on traveling to puerto rico and verizon has been inconsistent enough with how they describe their charges/coverage that i want to have a voip backup on my D4. I recall that Gingerbread is supposed to have integrated VOIP calling, but I can't find it! i've looked all over. any ideas where it's hiding on 2.3.6??
Barring that, any suggestions on the best SIP client to use? My provider is callcentric.
