hello all!

i have 2 people in my contacts book whose email address are different only by one character (e.g. 123456789A@mobile.mycingular.com and 123456789B@mobile.mycingular.com). When i try to SMS either, i select "to address by email address" and pick either and when i send Treo gives "invalid address" error (the address entered for this message is invalid. etc.etc) When i delete either one of the entry i would be able to send successfully.

Anybody encountered this? is this a problem with the Treo? I have a Treo 270 with GPRS1.1 on Cingular. How do i resolve this?

Thank you very much.
