Finally!! A simple, fast, "bulletproof" file transfer method!

Perhaps I'm not the most technically savvy but as much as I like and use iDisk and QuickOffice it is frequently a frustrating experience to get everything to connect via wifi and there is no way I've discovered to transfer files between my MacBook Pro and my iPhone without having both devices connected to a server.

Why is this important? Because I travel internationally and in a pinch have to e-mail files from my phone or receive them there because I can't get a connection for my laptop. With this app I can now easily and very quickly transfer files between my iPhone and laptop via good old dependable physical connection USB! This is a lifesaver for me as now, in an "emergency" situation I can send transfer any file on my laptop to my iPhone and if I've got a data connection I can e-mail the file. Likewise if I need something in an emergency I can do the reverse. Of course if I could actually tether my iPhone and use it as a wireless modem that would be nice but that is another story.

As for the viewer and file features, looks good but too early to comment. I'll come back at this after a couple of weeks and see if it deserves the 5th star!

Not bad, but not great...

Does not hide files while switching between apps. But otherwise it is ok. If you are worried about hiding stuff, completely close the app from the background. No problems view images or videos.

Worth giving a try

I searched all day for an interface that does this! I've given only four stars because it's brand new and hasn't been reviewed much yet - but if it stands the test of time I'll be one happy girl!!!
