The minor and isolated connectivity issues are not even close to a "debacle."
We see no evidence of widespread complaining besides a couple threads on forums. If this were major, we wouldn't have stopped hearing about it.
There is no doubt a bad batch of phones and major cellular connectivity issues . Apple needs to step up and issue a recall for the defective batch and fix the cellular issues asap ! Most people don't even know that they have phones issues till they test carefully by streaming stuff . You will see fake bars with no data flowing and dropped calls .
