I have a Droid X with the OTA Gingerbread update and I am looking for an app to use to make calls home to the US over WIFI while I am in Costa Rica. I had Fring and it worked fine until the GB update and now the mic doesn't work so it's worthless. I'm considering Vopium as an alternative...does anyone have experience with that app? Or is there another app that is recommended? Thanks for your suggestions.
