help really needed

[bossmav]

I post this request in another forum but I'm in so much trouble that I have to ask here.
For most husbands I'm sure you will understand, if you are not married yet and are a male reading this if you get married you will understand.

I just got my wife a htc 6800 from a local provider by the name of Ntelos, it only costed .99 cents because they are a discontinued model. Being the Mr.fix-it that I am, I tried the rom update to 6.5 with great success until my wife tried the data connection, now she has no email or internet.
Ntelos can't send the phone any updates using the ##778 and said since I've changed the rom I'm now stuck with this phone or I can buy a new one for $259.00. The phone came with windows mobile 6, I can't find a rom anywhere for this and after reloading the Justpctech 21501 Titan rom I've still had no luck. I can follow most instructions and have been networking computer systems for almost 20 years, phones are new to me but isn't windows windows?
If anyone has a idea how to fix this please post it.
Thanks in advance for any and all help.
