iPhone 4S loses signal
TL;DR: iPhone loses signal completely with no apparent reason, rebooting helps, but 4 times in 8h is a bit too often.
Hey there,
I was very excited when I got the new iPhone 4S today. Unfortunately after 30min it didn't get any signal anymore. I live in a big city and have normally a very high signal strength. I let the iPhone search for the network provider a few times, but it didn't find anything (the iPad2 lying next to it had full signal strength).
Rebooting helped, but after another hour or so (and disrupting a call twice) it couldn't find any signal again. So I rebooted and there it was again. So all in all I had to reboot the phone about 4 times in 8 hours.
I couldn't find any similar problems in the forum so is this a unique problem? Is it a hardware or software problem? can I do anything against that?
Here are some additional infos:
