I installed i Tunes 10.5 and I am pretty sure the firmware for the 2G phone is 1.1.3 (although I had attempted to roll it back).
ATT yesterday announced that its 2G wireless network was officially shut down on January 1, 2017.

There are some basic troubleshooting methods by which this problem can easily be resolved.
If you still happen to use an i Phone 2G, it may be time to upgrade or list it on e Bay.
Mac Rumors reports: Few people appear to have been using the original i Phone as there were no complaints from i Phone owners two weeks ago when the network was shuttered, but going forward, customers who keep the device as part of a collection will only be able to use it on Wi Fi.
Alternatively you can toggle “Airplane Mode” from control center. Please note the backup you just took on i OS 9 won't be compatible with i OS 8.4.1, it is just for security purpose.
