Samsung Hercules, an upgraded Galaxy S II is coming to T-Mobile this September to join the smartphone battle, a potential rival of iPhone 5.

Samsung Hercules is expected to come with 4.5 inch 800x480 Super AMOLED Plus resolution with a dual-core processor CPU 1.2 / 1.5 GHz Qualcomm Snapdragon APQ8060, this smartphone memory of 1 GB of RAM, 16GB of Flash storage, 8mp camera with LED flash plus video recording capabilities FULL HD.

Hercules with the NFC support will stand alongside Google Nexus S 4G, Samsung Galaxy S2, Samsung Wave 578, BlackBerry Bold 9900/9930 and Nokia N9 as all of them have NFC support. The iPhone 5 is rumored to have an NFC support but the UK carriers revealed that Apple will abstain from NFC as it believes that there is no industry standard related to the technology.

The mightiest of all its features is that the smartphone is having category 24 HSDPA capability to exceed the max speeds of 42Mbps downstream which will make the Hercules the fastest HSDPA plus for a smartphone in the market.

The phone will also have an MHL port which combines microUSB and HDMI port as one single port.

The smartphone is priced at $350 and is expected to have a big impact on the smartphone market.
