When Samsung unveiled Wave 578 at MWC, the phone sported a round center button. However, new images on the bada website confirm Samsung has modified the phone’s design a bit, which now has a rectangular home button. The button is reminiscent to what have in Galaxy S II and Galaxy Ace.

Apart from this, Wave 578 features same specs as before like bada 1.1 OS, NFC, 3.2” WQVGA TFT LCD, 3.2MP rear-facing camera and front facing VGA, TouchWiz UI, Bluetooth 3.0, Wi-Fi, QuickType keyboard input, microSD card slot and 1200mAh battery.

The phone is expected to go on sale soon.
