I saw another post like this but it was just on his iphone, not itunes from the computer or on the phone itself.

Basically I can acess all the apps from the Apple store, but cannot download any, previously purchased, free, new paid, or any to my iphone 3gs on 4.2.1 jailbroken with greenpoison last week.

Not sure when this problem arose, but it's been happening the last 3 or 4 days at least. Now I have no apple store apps (except the ones that come with the phone and can't be deleted) because when I connected to itunes it tried to sync all the ones in my library and deleted first.

I believe this is some issue with the apple store somehow not being able to connect to my iphone and load the apps, not an issue with anything like authorization or updates and so forth cause I've done all of that.

If anyone has any feedback, I would greatly appreciate it. Thank you very much. David
