Dual

Was looking for a new phone yesterday. Specifically I was interested in HTC's Touch Dual. I walked into the stores of a handful of carriers and asked them about the phone. I thought it had to be so long since I left North America that I couldn't pronounce the name of the phone right, because all the salespersons called it like Touch Deal, until online dictionaries like Merriam-Webster and The Free Dictionary helped me regain confidence once again.
