However, it just needs a few (rather minor) tweaks.
Xial:106495 contains only part of the message I received, just forwarded to my LJ from my phone (sending limitations, due to the phone.)
I can receive 120 characters in the body of messages, and 15 in the subject - a total of 135 characters.
the setting for cingular:houston allowed me to sent about 5 characters more than I could receive.
there were no additional messages, despite the "1 of 2" header.
