It looks like Samsung is getting ready to announce a new device that will be available on both Virgin Mobile and Boost Mobile. The company has sent out invites for an event that is taking place on Wednesday, August 22. Unfortunately, the RSVP card doesn’t say much about what is going to be announced. Will it be new phone or tablet on Virgin Mobile? How about a flagship device, such as the Galaxy S III? We’ll be finding out on August 22. Until then, keep the guesses coming.
