Phone? Tablet? Samsung calls it the Galaxy Note. The Android device with a massive 5.3 inch display was revealed earlier this year, but no announcements have been made about availability in the US. However, this week Samsung unveiled a newer Galaxy Note that includes 4G LTE and we have already heard rumblings that it will appear on AT&T early next year.

As a refresher, the Galaxy Note features Android 2.3 skinned with TouchWiz, a 5.3 inch HD Super AMOLED display with 1280 x 800 resolution, dual-core 1.4 GHz Exynos processor, 1 GB RAM, 8 MP rear camera, 2 MP front camera, S Pen stylus, 32 GB internal storage, and a 2500 mAh battery.

The current Galaxy Note (selling unlocked for $734.99) already supports HSPA+, so the addition of 4G LTE will make it a perfect fit for AT&T’s LTE network which recently expanded to 15 markets. AT&T plans to reach 70 million Americans with 4G LTE by year-end 2011.

Stephen Schenck of PocketNow recently posted pictures of the Galaxy Note with a 4-button layout common in the US, which also supports this device is head stateside.

With a larger display and better processor than the Galaxy Nexus, I think quite a few AT&T customer’s could choose the Note over Google’s flagship phone. Hopefully, AT&T has asked Samsung to upgrade the Galaxy Note to Android 4.0 before they bring it to market.

Anyone out there ready to carry a 5.3-inch superphone?

Update: As pointed out in the comments, the Korea Times is reporting the Galaxy Note LTE uses a Qualcomm Snapdragon processor and not Samsung’s Exynos. However, the paper reports the processor as “1.5-megahertz dual-core” when Samsung’s site still says dual-core 1.4 GHz. Basically, we don’t know which CPU the Galaxy Note will have when it launches in the US.
