Let me ask you this penguin, if I follow this link
I can find my way to software that will flash my phone's software to the last version supported by Tmobile.
Now, will doing this make my phone an officially supported Tmobile phone? For example, when I fire up my phone now it displays a Cincinnati Bell splash screen, will this software replace that screen with a Tmobile screen? If yes, does that mean my phone is now an "official" Tmobile device?
I'm just trying to exhaust all options before I send it back to the seller, plus I really like the phone and would love to keep it.
