Having the same issue except my carrier is T-mobile everything else is the same as djfento. This only started happening a few days ago, I think I may have inadvertently updated to the newest ver of ultrasnow which I'm guessing broke my sms. It was working for quite a while with the older .7 version with no problems. I spent quite a bit of time talking w/ tmobile about it and they tried to help to no avail, I actually used pretty much all those commands that you described mah6447 but they dont fix this problem . Does anyone know of a way to get access to an older version of ultrasnow to install?
