This doesn’t bode too well…

Per AppleInsider, multiple users on Apple’s discussion boards complaining that the recent iOS 5.0.1 update has lead to messages that read “Invalid SIM” and “SIM Failure” on their iPhone 4S users. This person said the errors began occurring after they updated to iOS 5.0.1, though other users posting on Apple’s official Support Communities website, in a thread with more than 30,000 views to date, have experienced similar problems since the iPhone 4S first went on sale in October.

“This problem can only be solved when you reboot your iPhone,” the person, who is an AT&T customer, wrote in an e-mail. “Everything else fails — restore, removal of the SIM, etc.”

When users experience a SIM-card-related error, basic functions including making phone calls, sending text messages, and using mobile data become unavailable, as the handset cannot make a connection with the wireless data provider.

The iPhone 4S is a “world phone,” which means its redesigned antenna and internal components are compatible with both CDMA and GSM carriers. Micro SIM cards placed in the iPhone 4S are only used by GSM carriers to identify a subscriber and grant them access to a carrier’s wireless network.

But while only GSM carriers, like AT&T in the U.S., use the micro SIM slot on the iPhone 4S, users on CDMA carriers, like Verizon and Sprint, have also reported experiencing SIM-card-related errors. iPhone 4S units sold through CDMA carriers come with a “roaming SIM” installed, which allows CDMA customers to roam worldwide on GSM networks.

“No service on my white 32 GB 4S on Verizon,” user ‘racyb’ wrote in October. “Did a shutdown and reboot….it went into searching mode and finally found Verizon again after 1 minute. What is going on?”

Since the release of iOS 5.0.1 earlier this month, another thread at the Apple Support Communities website features more users who say the problems began occurring after they updated their iPhone 4S. Some say their iPhone displays full signal reception, yet error messages like “Call Failed” and “Invalid SIM” continue to display.

“Same problem here in Brazil,” user ‘GuiMedrado’ wrote on Wednesday. “Bought my 4S – 32GB unlocked in Switzerland and couldnt’ make it work after upgrading to 5.0.1. Any solution?”

The iOS 5.0.1 update was released earlier this month in an attempt to address battery life issues reported by some users. But some battery-related problems have remained, and Apple has publicly said it is still working to fix those issues.

One rumor this week claimed that Apple will issue a new update, iOS 5.0.2, no later than next week in a second attempt to improve battery life with iOS 5. There was no mention of any fixes for SIM card issues or error messages.

Stay tuned for additional details as they become available and if you’ve seen this bug on your end, please let us know.

Apple looks into universal power adapter to charge MacBook, iOS devices

It’s the patents that make things interesting.

Per freepatentsonline, Apple has shown interest in building a new universal power adapter compatible with different DC voltage levels, allowing portable devices like a MacBook Pro, iPhone and iPad to be charged at the same time with just one wall plug.

The proposed invention was revealed this week in a new Apple patent application filed with the U.S. Patent and Trademark Office. The filing, entitled “Multi-Output Power Supply,” notes that most commercially available adapters do not include multiple outputs for supplying different DC voltage levels.

“As such, users may often purchase a device-specific adapter for powering a device,” it states. “However, this requires that the user carry a separate adapter for each device, which can be cumbersome when a user is traveling, as many users forget to bring all of the associated adapters required for various devices.”

Those adapters can also be relatively bulky, Apple notes, making them less than ideal to carry while traveling. The company also said that it can be confusing to users when multiple adapters are at use in a stationary location, like a home or office.

Apple’s solution is a new universal power supply that would connect to multiple electronic devices. This would make it unnecessary for users to carry multiple power adapters while traveling with multiple portable devices.

The filing describes a single power adapter that includes a DC-to-DC converter, allowing it to meet the different voltage requirements of unique devices. The adapter could also intelligently control power supplied through its outlets to ensure that the correct voltage is sent out to appropriate devices.

In addition to iPods, iPhones and iPads, the application specifically notes that such a system could also be compatible with Apple’s patented MagSafe technology, used to supply power to the company’s MacBook line of notebooks.

The charging cable could include a power “brick” similar to the ones currently used with a MacBook Pro or MacBook Air. That brick would include the necessary voltage converter, and could allow another portable device like an iPhone to be plugged in to charge.

The proposed invention was first filed by Apple in May of 2010, and was made public this week. It is credited to Aleksandar Pance, Nicholas Alan Rundle, and John Douglas Field.

The latest application is not the first time Apple has shown interest in redesigning its power adapters to allow charging of multiple devices. In September, another filing showed the company is interested in building a universal charger that would allow portable devices to not only recharge their batteries, but also sync data while plugged in to the same adapter.
