I've been having periodic problems with MAIL, in that it sometimes will not connect to server, whether I open mail acct or hit RELOAD key.
The only option is restarting the iPhone
The problem lies when I notice this as I am sending mail. Since it does not connect, the mail goes nowhere (and since there is only a SENT folder) the letter is forever lost.
As such, I am losing sent mail.
Any others w/ this problem
Yep - me. No idea how to fix it. Basically the device is unusable to send mail when it switches between 3G and wifi or where 3G signal is patchy. It doesn't seem to be able to rate a weak 3G signal against a strong Edge one - and so it seems to just fail. It's ok to receive mail, as long as you are willing to restart the mail programme several times, losing any items unsent as you suggest.
Don't get me wrong, I love my Iphone (before the weirdos crowd in) but the idea of this as a blackberry killer without significant improvement to the mail functionality is frankly laughable.
