Earlier this year, several pieces of evidence from the internal computer sales system for Canada’s Rogers Wireless suggested that an 8 GB iPhone 3GS was in the works, although Rogers representatives claimed that the listing was an error and no such model has appeared in the months since. Early last month, a new report claiming that AT&T was looking to deploy an 8 GB version of the iPhone 3GS before Christmas also surfaced, but again nothing materialized.

A new report from German forum apfeltalk.de, discovered by Electronista, has revived the speculation with news of a user who ordered a refurbished 8 GB iPhone 3G and received the proper model but in a box carrying a label reading “iPhone 3GS v2.2, 8GB”.

“After buying a refurbished 8GB iPhone 3G, the Hamburg resident received the promised device but with a label on the back pointing to an “iPhone 3GS v2.2, 8GB.” The model (A1241) and part number (MB490DN/A) point to the older model, but “iPhone 3GS” appears elsewhere on the packaging and implies that its mention wasn’t a mistake.”

It is unclear why such a label mentioning “iPhone 3GS” in several locations would appear at this time on a plain white box used for refurbished iPhones.
