I was on Sprint and T-Mobile bought Sprint. T-Mobile is robotically cruel to customers. T-Mobile is rule-bound and failure to comply results in employees being fired. Here's the difference:
I got a defective phone with sprint: phone replaced under manufacturer's warranty immediately.
Same defective new phone scenario with T-Mobile: no replacement because you didn't buy additional insurance - even though you got the phone a month ago. Sorry can't help. I wish I could help you but I will be fired if I deviate from the rules. Thank you for your understanding. Avoid doing business with T-Mobile at all costs. They are horrible.

So, I'm happily with AT&T now.
