When I call while roaming I get "If you'd like to make a collect call.." message every time try. I am rooted, but it did this before I was rooted. I am now on the latest CM7 and it seems to do it every time now, before cm7 it was about 60% of the time. On the stock htc rom it made no difference when i rooted it and I could make calls when roaming 40% of the time. I use roam control to test with, and tested calling from my house i used to be able to call from my house when I forced roaming now I get the same message I get in other places. I called sprint and got them to do an error 16/hrl signal re-sending thing, but I'm not sure if this works with a non htc rom. Sorry about my writing skills Oh and I've try different radios and stuff before the cm7 rom but not after as it didn't help then. I believe this has nothing to do with rooting and I just need to access some deeper setting on my phone maybe by using the dialer.
