Since it was rumored a few weeks ago , iOS would be by joining the channel public beta as we have today in OS X Yosemite, and now is official as it gets about Apple now has just updated its website to make way for the first public beta of iOS 8.3 .
All those who are already enrolled in the program and are receiving beta of OS X Yosemite will be registered automatically for the betas of iOS , which arrive via OTA to our device where we have turned our Apple account registered in the program.
But before receiving the first beta in our device or devices which want to use the beta, we must follow a series of steps as happens in OS X where we were asked to install a small program for our Mac has access to the beta.
In the case of iOS have to do a backup on our device in iTunes and then download a configuration profile from the website of Public Beta, install and thus gain access to betas via OTA.
The program has just been enabled in the United States and is expected to reach every country in the coming hours or days, so be patient and wait.
