I pay full on time every time. I do not abuse bandwidth (no jailbreak tethering or excessive web use).
Additionally, there are people who pay over $100 a month yet they're in December or March while other people with the same bill are in July of this year.
There are obvious and unexplained variations in the upgrade eligibility. Yet we are getting people in here calling everyone whiners or cry babies. Yes, how dare we ask for explanation for the seemingly random eligibility. Lets just keep beating that strawman.
Well, if your situations were EXACTLY the same and have different eligibility dates then it's At&T. But I doubt you'll be able to get an answer from them unless you have the "other person with exact situation" talking to them at the same time and give them the Ok to pull up both accounts to determine why there is a difference. I would LOVE to hear their explanation.
