is there a travel app comparable to blackberry travel?

Perhaps you could describe the features you're looking for in a travel app. Most of us here probably don't have Blackberries and may not know what the Blackberry Travel app does.

Best of luck.

There are a ton of travel apps available via the App Store.

Have you checked the App Store?

I put the relevant parts of your post (automatically installs all emailed travel confirmations onto my outlook acct Airline reservations, car rentals, hotels) and followed by "iphone" into Google. The top answer is probably what you're looking for but there may well be others.

Best of luck.

I gave you the directions on how to search Google to find the kind of application you want.
