I have a Yahoo account, but it ends with swbell.net instead of yahoo.com, because ATT (previously SBC, previously SWBell) uses them for their customers' email. Anyway, after the previous iPhone update on August 2, I couldn't send email with that account. People reported talking to Apple, Yahoo and ATT, and each company would point the finger at another. I was convinced it was an Apple issue, something related to not realizing that people could have Yahoo accounts that don't have a yahoo.com address. For example, I had to configure the account as "firstname.lastname@example.org@yahoo.com." I figured that during the Aug 2 update, Apple changed something that broke that workaround. Looks like I was right, because with the 1.1.1 update, the address field for a Yahoo account is free-form, and I can now send email with that account again. Not too many people posted up about it, I guess only a few of us still have our old swbell, sbcglobal, etc., accounts. But it's nice that Apple fixed it. I just wish the did it sooner as a separate update, rather than wait to bundle it up with lots of other stuff.
