txtforward on mac mail os.10.5.5

Alright so i just bought the txt forward app for my bold
i have my address book synced using pocketmac to my address book on my mac
when i get a text forwarded to my gmail account which is on the mail application on my mac, i see the text from the number not the name of the person it was sent from even tho my address book is synced to my mac

Is there anyway i could have it so that it shows the name of the person and not the number?

I'm running OS. 4.6.0.216 on my AT&T Bold btw but i dont think thats relavent.
thanks in advance for any help ; )
