PPCGeeks - Specifying your own DNS Servers

Hello,

I have a HTC PPC-6800 running Windows Mobile 6. Is there a way for me to specify my own DNS servers instead of having the device use my cell phone carriers DNS servers?

I recently moved my domain to a new set of name servers, and changed all the zone records to point to a new IP. It seems mostly all the DNS servers I use have updated and reflect this change now except for my Carriers DNS. This domain hosts my e-mail so i'm not able to check e-mail on my phone right now. It's been over 24 hours since the changes to the domain were made.
