Based on a User Agent Profile, it sadly appears that the unnamed Samsung executive was right on target. The User Agent string in question shows a handset with the model number SCH-I535 with a 720p display and powered by Android 4.0. Under the hood is the Qualcomm MSM8960 processor which is the S4. The model number seems to fit in with traditional model numbers used by Verizon for Samsung branded smartphones such as the Samsung GALAXY Nexus (SCH-I515), the Samsung Droid Charge (SCH-I510) and the Samsung Fascinate (SCH-I500).
As we discussed before, quad-core processors like the NVIDIA Tegra 3 and the Exynos processor do not offer an integrated LTE radio like the S4 does. So far, those chips and LTE just do not play well together and with more and more Stateside customers turning to LTE, Samsung might have no choice but to turn to the S4. But the S4 does have plenty of fans and has proven in benchmark tests and in real-life usage to be extremely zippy.
We should learn a lot more about the Samsung Galaxy S III on Thursday when the device is expected to be introduced by the manufacturer.
