Oh T9 text messaging, how I love you so. Too bad I will soon have to kick you to the curb for the new and improved XT9 "mobile interface" or text messaging. XT9 is being developed by Tegic communications. The biggest and really only important upgrade is an updated word prediction list and spelling correction. XT9 recognizes common spelling mistakes and will correct it for you. Have no idea what I'm talking about with T9 and such? Ask your kids, they'll know.
