iPhone error cannot "connect to iTunes store"

hi

i got this error while trying to download an application. 'Cannot connect to iTunes'.

I had already my own user and password.

To resolve it I had to register again on the iPhone for a new user. Once i placed all my old profile info in the registration on the phone. It told me that user already exists. Than it asked me if i want to use this profile on the phone. Once i said yes. everything worked normally after that.

hope it helps. This happen after a fresh install of a jailbreak.
