Here are some improvements to consider:

import string
def main():
     d = {"1" : phoneTranslator, "2" : backwardString}  # map user 
selection to corresponding function
     while True:
         selection = raw_input("Enter you choice. Enter 1 " +
                        "for Phone Translator or 2 for Backward String.")
         operation = d.get(selection, None) # retrieve corresponding 
function or None
         if operation: # did we get something?
             operation() # call it
             break # out of the while loop
         print "Invalid choice"

def phoneTranslator():
     trans = string.maketrans("ABCDEFGHIJKLMNOPQRSTUVWXYZ", 
"22233344455566677778889999")
     print "Phone Translator "
     phoneNumber = raw_input ("Please enter the phone number: ").upper()
     phoneNumber = phoneNumber.translate(trans)
     print phoneNumber[:3] + "-" + phoneNumber[3:]

def backwardString():
     print "not implemented"

main()
