Pete,In the built in mail client: if I have a number of email to read how can I jump to the next unread mail without closing the current mail going back to the inbox and selecting the next one. On the Desire I would simply click an up / down arrow to move between emails.
Just swipe left or right to go to the previous or next email.
I've just tried it in the standard email app and in the gmail one, both work the same.
