Erasing PkgBackup Data in Contacts

[downingp]

I recently upgraded from an iPhone 4 to 4s. My iPhone 4 was previously jailbroken, however prior to switching to the 4s I upgraded the 4 to iOS 5 and obviously lost my jailbreak.
With my 4s, I am obviously on iOS 5 and am using iCloud for contacts calendars etc. When I go into my contacts I see contacts on iPhone, which is empty as well as a PkgBackup folder. There is nothing in the PkgBackup folder and was wondering how I could delete the folder from my phone. As a side note, there is not a PkgBackup folder in my contacts on my Mac.

Thanks.
