Previously, an Italian Web site, Telefonino, revealed a list of Samsung’s upcoming smartphones that was leaked to it. Three models in the list were the Andorid-based GT-B5510, the S5360 and the S5610. The first model is expected to run Android 2.2 (Froyo), while the other two will be running on Gingerbread juice.

Telefonino said that the 2.8-inch B5510 will have an 800MHz chipset, a three-megapixel rear camera, Wi-Fi and a physical QWERTY keyboard. The other two will arrive with a 3-inch and a 2.4-inch screen respectively.

Samsung, however, said in a statement that the news regarding the roadmap for its smartphones and tablet that should arrive later this year are not accurate.
