T5 and Treo 650, and skus

Hey there guys...okay this is gonna sound weird but i gotta ask you guys a few questions..

1. I remember reading that the T5 and Treo 650 share the same type of connectors...meaning a T5 accessory (ie a cable or power adpater) will work on a treo 650 right?

okay the reason i am asking is for the reason that...in a store in canada called Compusmart...they are selling T5 accessories...and wellt he cords and a/c adapters look exactly the same for that of a treo 650...and well if they are the same..the prices are truly very nice..

thanks guys for the help

moo?
