T-Mobile moves up Vibrant launch date to July 15

We reported earlier that AT&T confirmed a July 18th date for the Captivate, its Samsung Galaxy S variant. It was rumored that T-Mobile was moving up the launch of its own Galaxy S variant, the Vibrant from July 21 to July 15, and that has now been confirmed, also.

While unclear if the reason for the Vibrant's bump by six days is the Captivate, it is wouldn't surprise us if that were the case. Both Sprint (Epic 4G, with slide-out keyboard) and Verizon (Fascinate) will also carry Galaxy S variants, but obviously since the Galaxy S is a GSM device the U.S. GSM carriers were going to get it first.

All of these Galaxy S variants will have a 4-inch Super AMOLED, a 1GHz Samsung Hummingbird CPU, Bluetooth 3.0, and Android 2.1. The Vibrant and Captivate will both go for $199 (with a 2-year contract), and the Fascinate and EPIC 4G will likely be close in price, though the 4G's slide-out keyboard might raise the price some.

However, neither the Vibrant nor Captivate will have LED flash, and the Captivate will not (as seems to be the case with all AT&T Android devices) allow sideloading (non-Android Market apps). On the plus side, both of those will have 16GB of internal storage, while the Fascinate will only have 2GB and the Epic 4G 1GB.
