By way of introduction let me say that I am in my sixth decade and am addicted to gadgets. I use my Touch at work for the calendar, calculator, address etc features and have a number of applications loaded which help me keep track of my dwindling stock value and the weather. I have bonded with my Touch and get "out of sorts" when it does not work propely. I am currently having a problem with the sending messages on Wi-Fi and get the following error statement "Cannot Send Mail--the sender address was invalid". This only happens when I am away from my Wi-Fi hot spot at home. I have posted a query about this problem and hope some one will have a solution for me. Thanks and best wishes to you all.
