The latest rumour comes from website An3DBenchXL which displays benchmarking results for a device named "Galaxy S 2+" with the uploader name "Samsung".
The results show the rumoured device having a 1.5GHz processor – a step up from the 1.2GHz dual-core chip found in the Galaxy S2.
Extra power but no ice cream in sight
Disappointingly it also shows the Galaxy S2 Plus running Android 2.3.4 which isn't even the latest version of Gingerbread let alone Ice Cream Sandwich, the 4.0 version of Google's operating system.
Update: Industry insider Eldar Murtazin has posted an image of a Samsung handset on his Twitter, with the simple words: "Barcelona. Samsung. Press photo leaked". It looks suspicously like the Galaxy S2, but is clearly sporting Ice Cream Sandiwch - could this be the Galaxy S2 Plus?

The last hint the supposed benchmarking results provide is the screen resolution which it shown as 800 x 480. This is the same as the current S2, but that's no bad thing as the screen is exceptionally good.
The Galaxy S2 Plus could be Samsung's attempt to re-fresh the Galaxy brand and build hype before the S3 launch later this year - plus gives it something to talk about in Barcelona.
