Two new smartphones with the largest screen sizes available are coming soon to AT&T, and the HTC Titan II and Samsung Galaxy Note will stand out for more than just their size. Both will join AT&T's growing corps of 4G LTE-enabled devices.

Titan II runs the Microsoft system and the Note includes a stylus. This is noteworthy because Titan II is the first Windows Phone device to run on the LTE network, and few tablets include a stylus, let alone smartphones.

Neither device has a release date yet, or even a price, but they should both be ready soon and are not likely to cost less than $200 with a new two-year contract. HTC's original Titan smartphone goes for $200 on contract, so the Titan II could debut at  $250 to $300 unless they go the iPhone route and drop the price of the Titan and debut the Titan II at $200.

It's harder to predict what the Galaxy Note will go for, but $300 would not be surprising given its 5.3-inch screen size. It's approaching tablet land with that, and that could be enough for AT&T to give the ultra-premium price. Additionally, the Galaxy Note has an impressive resolution on that giant screen. Pixel density is often a more accurate way to measure mobile device displays, and the Note has 285 per inch. For comparison, iPhone 4S has 330 ppi (with a much smaller screen), so Galaxy Note will impress almost everybody with the screen size and resolution combo.

Of course, that doesn't mean the HTC Titan II display is junk, but because it is a Windows Phone device, it is more limited hardware-wise. Microsoft is strict with its manufacturer hardware requirements, and because of this, the Titan II will mount a display with about half the resolution of the Note. It also will debut a 16 megapixel rear-facing camera and front-facing camera for video chat. Most other Windows Phone devices don't have the front-facing camera.

Furthermore, the Titan II comes with a 4.7-inch screen, 16 gigabytes of storage and is about 13 mm thick. The Note will debut with front and rear-facing cameras, 16 gigabytes of storage (expandable to 32GB with the microSD card slot) and Android 2.3. Android 4.0 will be available soon after the Note debuts, but Samsung hasn't given any details on that.
