A tiny bit of uncertainty has been cleared away thanks to good old Twitter, where T-Mobile has made July 15 (aka, today!) the official launch date for its Galaxy S derivative, the Vibrant. The original Tweet seems to have disappeared into the ether apart from that screenshot above, but T-Mo has reiterated the statement in subsequent missives, telling its followers that the Vibrant will be on sale today. We imagine the typical $199.99 price point will remain unaltered, so all you'll really need to do now is decide whether this is the Super AMOLED handset for you, or whether you can wait the extra few days until Sprint et al intro their offerings. Decisions, decisions.
Update: And it's now available to buy directly from T-Mobile's online store [Thanks, Volaris].
