AT&T just announced the Galaxy Note at their on-going Developer Summit at CES 2012. The news of this smartphone-cum-tablet coming to the carrier had leaked quite a few times before so it’s not really a big surprise.

Externally, the AT&T’s version of the Galaxy Note is similar to its European sibling except for some minor differences. While the beautiful and HUGE 5.3-inch HD Super-AMOLED display with a mind-boggling 1280×800 resolution is intact, the 2 capactive,  1 hardware key combo has been replaced by 4 capactive keys.

Internally, the difference between the European Note and the AT&T version is quite huge though. The AT&T version packs in a 1.5GHz dual-core Qualcomm Snapdragon S3 processor, an Adreno 220 GPU and 1GB of RAM. All other usual features like accelerometer, gyroscope and connectivity features like Wi-Fi, GPS etc. are also present. The Note will also support’s AT&T’s new and blazing fast 4G LTE network.

Sadly, AT&T did not mention anything as to when the Note will hit its network or how much it will cost.
