After the “unprecedented demand” and supply issues encountered by AT&T and Sprint, the first two US carriers to sell the Galaxy S3, few were optimistic about Verizon’s own launch of the super phone.

Big Red had already lost “points” in the eyes of its customers by announcing it will launch the S3 weeks after Sprint and AT&T. The user frustration grew even deeper when the initial launch was pushed back from July 9 to 10.

In an unusual and surprising turn of events, however, Verizon seems to have started the S3’s shipping process way ahead of schedule. Droid-Life and Phandroid have reported yesterday on rumors that pre-ordered phones will start reaching customers as soon as July 5 (yes, this Thursday!), and many users have confirmed the speculations over the last 24 hours.

A bunch of shipment notifications with arrival dates of July 5 or 6 have been sent by Verizon to users who’ve pre-ordered the phone back in June. Unfortunately, not all Galaxy S3 adopters over at Big Red will be so lucky. Many customers are reporting that their online order status hasn’t been updated and they still don’t know when they’ll be able to get their hands on their spanking new phone.

Is there anyone reading us who’s received the shipment notification from Verizon? Please let us know in the comments section below.
