I was saying in a previous post how I couldn't get the cookie for Yahoo! Mobile to be sticky on my Treo 600. I found last night that if I used wap.oa.yahoo.com/raw?dp=home instead of just wap.oa.yahoo.com, the cookie becomes stickier. It stuck for most of the time I tested last night, including leaving the Yahoo! network, leaving the app and coming back. But, this morning, it was gone. Maybe there is an expiration on the cookie or something. Now, here is one way that will make the login go away completely, but is somewhat insecure: http://wap.oa.yahoo.com/raw?dp=auth&src=home&login=user&passwd=pass Replace "user" with your username and "pass" with your password. Save this as a bookmark, and whenever you go to it, you'll be logged in automagically. I found this tip on HowardForums. Use with caution.
