Sprint sucks
Sprint cannot even do 1G right. Why should I trust them to do WiMAX right? Nobody drops more calls than Sprint. Nobody is harder to contact than a customer with a Sprint mobile phone. Nobody is more frustrated than a person talking a Sprint customer rep. There reps are downright rude to you. And when Spring does VoIP, it costs 50% more than their competition yet delivers inferior service. Sprint cannot do anything right. So instead of trying something new, Sprint should get what they have right first. After all, if I cannot trust you do the easier stuff, why can I trust you to do harder stuff?
