the day prior to this, we cited that Apple had quietly launched a tweaked version of iOS 5.0.1. the purpose of the tweak was a mystery given that the replace was once not being pushed to all users and only made to be had to these newly updating to iOS 5.0.1. the brand new version arrived as build 9A406, and increment of 1 over the original iOS 5.0.1 free up.
however in response to a new Apple give a boost to record, it now seems that the updated build may have been designed to address an issue some customers were experiencing with SIM card-related error. With the replace affecting a relatively small component to users, Apple can have elected not to push it out to all customers within the form of an iOS 5.0.2 tool replace, and as an alternative rely on these users who are having problems following Apple’s recommendation and obtaining the brand new build through the restoration course of outlined as an answer for the difficulty.

last month, some consideration was became on Apple as a quickly-growing thread in Apple’s dialogue boards published a lot of users experiencing issues with either a “No provider” or “No SIM Card put in” warning taking drugs on their iPhone 4S devices. From Apple’s new beef up report:
In sure scenarios, iPhone 4S will have difficulty recognizing a micro-SIM card, resulting within the following behaviors:
– “Invalid SIM” or “No SIM Card put in” alert seems intermittently.
– status bar displays “No service” or “looking” in a place with just right network protection.
Apple goes on to explain the advisable answer for the problem, which entails backing up and then restoring the tool, an motion that includes iTunes pulling down the brand new build 9A406 of iOS 5.0.1 and putting in it on the person’s tool. once the instrument’s system has been restored, the consumer can then fix content material and settings from a backup.
1. back up your person content and settings the usage of iTunes or iCloud. See this text for extra knowledge.
2. repair your iPhone 4S using iTunes.
three. After the method is full, fix your person content and settings out of your backup.
four. to verify that you’ve got successfully restored, verify that the version is now iOS 5.0.1 (9A406) in Settings > common > About.
unfortunately, consumer reviews on the brand new construct seem like combined, with some users reporting that it does certainly fix their “no SIM card” concerns while others have seen no growth. it’s doubtful at the moment exactly why outcomes are combined and whether the restoration addresses only some subset of the foundation reasons of the difficulty or if another issue is in play. because of this, we could have to look forward to more customers to try making use of the replace before drawing more explicit conclusions.
