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
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.
