I'm on Cingular and I purchased the T-Mobile MDA and unlocked it. I was just curious if it was possible if I could erase the O.S. that T-Mobile incorporated with Windows and install the O.S. that Cingular has for the 8125...

Thanks in advance...

Yes this is possible.
If you would like a custom ROM look here:

If you would like the official Cingular ROM look here:

thanks bruh...how would i delete the old rom?

When you flash with the new ROM the old ROM will be replaced. It's kind of like re-installing Windows or Mac on a computer.

What you need to do is unlock you wizard first then you can flash with whatever ROM you like.

Look over this:

Heck you might even find that you want to install a custom ROM.
