Ken,
I don't use pocketmags, so I don't know if this is any help.
IF you have the facility to save the mags [or parts thereof] as PDF, then I would recommend GoodReader.
Unfortunately, Apple [post- Steve Jobs] seems determined to make the older devices obsolete, simply by encouraging App Developers to update their Apps to support the latest iOS, but not permitting them to provide backward compatibility.

Edit: Sorry … unless you already have GoodReader; it's too late
… minimum iOS for the current version is iOS 6
