iTunes beta, Vodafone flag up iPhone 4S
8GB iPhone 4 makes a pre-release appearance too
Evidence is building that Apple will indeed announce the iPhone 4S tomorrow.
References to the 4S have been spied within the pre-release version of iTunes 10.5 being provided to iOS 5 developers, 9to5Mac reports.
String data suggests that the 4S is the 'N94' handset that has been much mentioned in rumours through 2011, and that its model number is 'iPhone4,1'.

To muddy matters, the 4S is seemingly referenced only as CDMA phone.
Separately, Gizmodo's Brazillian offshoot has posted a snap of an iPhone 4-like front panel allegedly tagged with the code 'N90', suggesting to many pundits that this is the anticipated low-cost iPhone 4, possibly with 8GB of storage.
But the best evidence for the 4S comes from Vodafone Germany, which apparently added the handset to its website in both black and white forms, each with a choice of 16GB, 32GB or 64GB of storage, according to German-language site iPhone-Ticker.de
A screengrab from MacRumors also shows the presence of the 8GB iPhone 4 in both colours.

COMMENTS
"They will all make and receive phone calls."
Ooh, a new feature.
Smoke and mirrors - references in beta are often wrong to ensure confusion reigns. A new version of iTunes will be punted along with the (already announced) iOS 5 release, so it makes sense the new hardware will be named the iPhone 5.
Here's how it will work
Three models:
iPhone 4S - [NEW!] - 8Gb version of iPhone 4, with shiny plastic back instead of glass. May not be iOS5 capable.
iPhone 4 - will stay unchanged in 16 and 32Gb versions. iOS5 capable with some missing functionality.
iPhone 5 - [NEW!] - Larger screen (same res though), tapered edges (a little like iPad 2), metal back, re-worked antennae, 32Gb and 64Gb capacity; iOS 5 capable.
They will all make and receive phone calls.
iPhone 4S reference has been in iTunes beta for some time now:

So, the "iPhone 4S" reference first appeared in the iTunes Betas back in iTunes Beta 6.1 which was released on August 29th, 2011 -- a little over a month ago. [/quote]
