As you may know, Linden Lab has been working on a Second Life app for mobile devices. Last month, it looked like one would be soon be available in beta. But it appears the wait will be a little longer. In the Web User Group meeting held on Wednesday October 7, it was revealed that a beta version of the IOS (iPhone Operating System) version of the SL mobile app had been submitted to Apple to appear in it's app store, and was rejected. The reasons for the rejection were not revealed, only that the Lab is working to correct the issues.
For now, the IOS app remains in closed alpha. The Android version is described as behind the IOS in development.
Unrelated to Second Life but of note to gamers, Apple has been at odds with Epic, the company behind the popular Fortnite game, over what both sides claim is unreasonable behavior. Apple took Fortnite off it's app store over what it called violations of the agreement between them and Epic. A week ago on October 9, a judge ruled that Apple didn't have to put the game back.
