Braille and VoiceOver

Hello. I use an iPhone 5 with a Focus 40 Blue display. The other day I did something VoiceOver didn't like and it went away. VoiceOver failed to come back with the three home button command. After various attempts, I took it to the Apple Store because there was nobody with working eyes around. The tech got everything working again; or so I thought. When I got home I found that I had to re-enter my e-mail password and Wireless settings, which I managed to do. Then I attempted to use the focus 40. I found that it was not recognized automatically. When I attempted to turn Braille on, I found no list of drivers, and a message saying "searching" on the iPhone. The other thing was that I was presented with no Braille display choices. My suspicion is that the tech did some kind of reset on the phone, and I must beg forgiveness for the fact that my most recent backup would restore a date just before I updated to the latest version of OS5. Needless to say, I'm being driven nuts with no driver. Has anyone had a similar experience? Joe Fallin
