After the Samsung Galaxy S event today in NYC, attendees were given time to play around with the newly announced devices. Lucky for us, a few of the attendees managed to shoot some hands-on videos of the upcoming T-Mobile Samsung Vibrant. So far, first impressions seem to be pretty postive. Mark your calendars for July 21st and remember you can pre-order too! We've queued up some quick hands-on reviews of the Vibrant below. Leave your thoughts in the comments!
