Today’s mobile news roundup features the following: US carriers now accepting preorders for the Samsung Galaxy SIII, PlayStation gets deeper into mobile with HTC partnership while Apple waits for the Samsung injunction.

Samsung Galaxy SIII preorders now open

In yesterday’s mobile news roundup we mentioned that five US carriers will be selling the Samsung Galaxy SIII starting this month of June, but the release date and pricing were still a bit of a mystery.  The latest news on this matter now indicates that AT&T will start accepting preorders for Samsung’s new flagship phone starting tomorrow, June 6th.

The Samsung Galaxy SIII will be available for $199.99 for the 16GB model with a two-year contract, while AT&T stores will also sell a 16GB MicroSD card at a low price of $39 for a total of 32GB for only $238.99.

“The addition of the Samsung Galaxy S III to our portfolio of 4G-LTE devices gives our customers another truly cutting-edge smartphone to choose from,” said Jeff Bradley, senior vice president, Devices, AT&T Mobility. “With an exclusive red color this summer and the power of the nation’s largest 4G network, AT&T delivers the best wireless experience for Galaxy S III fans.”

As mentioned yesterday, the Samsung Galaxy SIII will be known just as the Samsung Galaxy SIII across all the network carriers, making it the most streamlined Samsung smartphone to date.  Not only will it be called the same thing across various carriers, but it will also be featuring the same things across the board so consumers won’t have to get confused as to what makes an AT&T Galaxy SIII different from the Verizon Galaxy SIII.

In other Samsung news, at the Computex show in Taipei, the South Korean company showed off two Windows 8-based tablets with attachable keyboards, due out by October of this year.

The tablets, the Samsung Series 5 Hybrid PC and the Samsung Series 7 Hybrid PC, both run Windows 8, feature 11.6 inch touchscreens, and a battery life of about seven hours.  Since they are still in the development stage, few technical specs were revealed but Samsung assured that they will be equipped with Intel chips.

Sony PlayStation goes mobile with HTC

Back in February it was rumored that Sony will be partnering with HTC, which will give the OEM access to Sony’s PlayStation Suite platform and offer PlayStation-certified mobile devices.  The rumors are true and with the partnership, the Sony PlayStation Suite was renamed to Sony PlayStation Mobile.  The new Mobile suite will be packed with PlayStation Certified games, ready be downloaded on Sony-partnered devices across the Android landscape.

The HTC One X and the HTC One S are the devices which caught Sony’s attention, deemed the perfect devices to play their awesome selection of PlayStation-certified games.

Apple awaits injunction request against Samsung

Apple’s injunction request against Samsung’s Galaxy Tab 10.1 was shut down by Judge Lucy Koh stating that “she wanted to wait until the United States Court of Appeals for the Federal Circuit had formally filed their ruling.”

Koh added that there’s a possibility that the court could “rehear the matter, alter or amend the opinion or otherwise change the scope of issues that must be addressed on remand,” adding that any injunction she granted now “would create confusion.”
