Q: everytime i try to use passbook i get error message cannot connect to itunes store but i am connected

Here's a fix I found:

Settings> General > Cellular > Use Cellular Data For: > iTunes > ON

Doesn't work for me. I have an iPhone 4s on At&t with iOS 6.0 and I have not been able to get Passport to open it's app store in itunes yet. Seems to only be working for the iPhone 5 users.

I have an iPhone4 with iOS 6.0.  I have yet to be able to open/do anything with Passport.  Tapping the icon gets me the "cannot connect to iTunes".  Tried your fix "Settings> General >Cellular >Use Cellular Data For: > iTunes > ON" -- does not work for me either.  This is getting ridiculous.  I see this is a problem for lots of people -- when ya gonna fix this, Apple?

I read somewhere to change the date ahead by 3 or 4 months (have to take off "Set Automatically) in Settings/General/Date and Time, and then go to iTunes from Passbook.  After it works, turn set automatically back on.

It worked for me.

I keep reading about this trick, but it doesn't work for me.
