Iphone was locked out over night. Now it says iPhone unavailable.

I sleep with my phone on the bed. Somehow the phone was locked out overnight and required me to connect it to iTunes on my computer and attempt to install the latest update. I attempted the iTunes connection/Recovery process this morning twice. The first time it asked for passcode 3 times and only accepted the first 2. Since I didn't want it to totally lock me out again, I retried the recovery process and now it says iPhone unavailable and won't go past that screen. I tried chatting with apple support but it says they are unavailable right now. The only other option it has is to speak with them by phone which I obviously can't do. Anyone else have this issue? Please help if you can. Many thanks in advance for any information that can be offered.
