I don't know if this is because they're starting to switch but I was with my friend yesterday and and he had to call his brother, Jake. He called him and got an automated voice answering machine that said "this person in the alltel network cannot be reached blah blah blah" then we called back about 2 or 3 hours later and it said "this person in the verizon network cannot be reached blah blah blah." I hope this is a sign that says it's coming soon!
