Alltel Titan thinks it is a Sprint.

[theerik]

I started at a new office and everyone has the titan. There was one guy they all took the phones to for cooked roms. Me being lazy let him do it for me and he flashed it with sprint. Now I have no data connectivity and after spending a few hours with my alltel rep, he says that alltel can't help me because it was overwritten with Sprint info.
I browsed the forums, I hope I didn't miss a topic with this issue. I was wondering what I would need to do to reclaim my phone and make it work again. I can still call and text, but i can't do a lot else.
