Thanks for the response. So do you think it only has to do with the phone being not Application unlocked? Didn't get the hint that it's saying it can't install the Xpressmail software, it successfully loaded in my phone. The only problem is that it's just missing that one piece of the client which is the email profile.
I tried playing around with Registry settings last night in trying to trick Xpressmail that it's a Cingular 2125
It didn't work. I compared registry settings that's common to them in terms of what's getting registered in the list of Xpressmail's devices. It seems it has two common areas (that makes sense) that can be modified to trick Xpressmail:
HKLM|Ident|OrigName|Value Data= 2125
HKLM|System|Platform|OEMString|Value Data= 2125
HKLM|Ident|OrigName|Value Data= T-Mobile Dash
HKLM|System|Platform|OEMString|Value Data= T-Mobile Dash
The only thing I can change on the Tmobile phone registry was the OrigName and the phone itself is not allowing me to change OEMString value. I tried the change on one registry entry and didn't work. I wonder if I could just change the Tmobile OEMString value to 2125, it might probably have worked.
Yeah if you could post me to get that tool, I won't mind experimenting to see if it will do the trick.
