we had one day where 3 blackberrys could make calls on our wifi with no signal, this was early last fall, i have nextel, one was at&t, not sure what the other was, however we have not been able to do it since, is there at least something i can get to send and recieve text via wifi? all the old threads i searched were over a year old, has anything come up? i know the iphone is good with skype to make calls over wifi. any help?
