  Confirming today's information, Apple Lossless Audio CODEC (ALAC), launched this evening iOS beta 7 4 for all compatible iDevices. The new build comes 3 weeks away from iOS beta 7 3, the problems generated by the exploitation of the portal dedicated to fortand developers Apple Lossless Audio CODEC (ALAC), to postpone the release scheduled last week. Separately from this build, Apple intends to release two more beta versions iOS 7, with the release of the GM version taking place in September, with the final version arriving in iTunes two weeks later.
