why dont you ask the creator of Galactic Wars 3 if you could use his keyboard/keypad? It looks fine and works very well...or if you dont want to do that specifically, (you said you suck at graphics, ask the creator of BLACKOUT for the little squares (preferably when the light it out so the button is black.) and place letters in the middle of the square.
Ideas:
space bar: on the keypad or some external button (as said before

lay to space, hold play to send)
Main Menu: should Include: INBOX (received texts), SENT (self-explanatory) OPTIONS, EXIT
Inbox: From main menu-select inbox and press center button. There should be a number in parenthesis to let you know how many messages are in the inbox and another number beside that one to let you know if there are any new texts
Sent: saved sent messages for resending or just viewing some old texts
Options: Music, music volume, Music chooser, delete message, delete all messages, etc.
Exit, exit texter
and for the texting screen:
needs backspace
For conversation screen:
also, if you wanted to we could text via inbox and sent boxes, or do it like yahoo instant messenger and type in a message and hit the send button (or hold play) then it will switch to a message log screen where the real conversation is between two parties.
Zune Names to clerify who sent what message
can I also suggest using the zune sideways for this or have a portrait/landscape option for this? And also, I know you said that you threw this together haphazardly, but can we text more that just a few characters? just some ideas......
but thank you for actually doing this, AMAZING!!!
