I notice that when I turn on the personal hotspot 4.3 ATT it works great as long as I am connected to it. Once I am no longer connected to it, it will stop broadcasting the SSID after a few minutes and I have to go into the setting again for it to start broadcasting. I do not have to switch it on to off to on just go into it. It is still set to on. Can anyone confirm this? I assume it is by design since Apple is so strict about things running that use battery life. Its a good thing.
