I currently have a Tmo SDA. I sync all my email on it as well as my appts, contacts, and tasks all through my Exchange server. The phone runs Windows mobile 5 and has wifi. The one thng lacking is a qwerty keyboard. I currently use a ThinkOutside bluetooth keyboard but I thought having a qwerty keyboard built in would be great. What do you all think of your E61? Would I be wise to sell my SDA for an E61a Thanks for your advice.
