Initially hinted by John Gruber of Daring Fireball, in connection with the first iTunes Festival in the US, several sources say that the release of an iOS 7.1 update is imminent. Previous reports had indicated that 7.1 was likely to arrive in March and adding to the fact that Apple has recently released new deployment tools for use in business and education environments, it looks like they are on track for the release soon. Apple is expected to update its iTunes Festival iOS application to support live streaming of the concerts from the SXSW festival, which runs from March 11th to the 15th, and according to Gruber, the new app requires iOS 7.1. That’s not a lot to go on, but it seems pretty solid, so keep your eyes peeled and software update button ready for the next few days.
