One thing I'd like to add. Yousendit has an iphone app that is quite useful. Is there one coming for SendNow?
I've branched your suggestion for the iphone app to the Adobe SendNow Ideas forum - thanks for taking the time to let us know.
Last I got a reply back from Adobe re/this same suggestion (an iOS app so I could resend/etc. while on the go) I was told that, since SendNow was Flash-based, I shouldn't expect an iOS App at any point in the near future. I sure hope that was wrong; an iOS app would be most useful.
This flash thing is getting tired. Frankly, there's no reason the desktop app should use Flash in the first place. Besides, is it so hard for Adobe folks to write an iOS app? Come on!
