I love that I can now pair my wireless keyboard to my iPhone 3GS running iOS 4. I've been enjoying typing e-mails and SMS messages much faster than I am usually able to with the touchscreen.

My question: is there a keystroke combination that will send a SMS text message when I've finished composing it? Lacking this, I'm stuck having to touch the "Send" button on the iPhone screen after typing the message itself out on the wireless keyboard. (I know, I know. Woe is me.)

NB: ⌘-S on the keyboard works to send an e-mail composed in the Mail app, but unfortunately has no effect when composing an SMS text message. Pressing the keyboard's return key simply produces a hard return (as you'd expect).

Thanks, all!
