Apple has updated one of the hundreds of technotes detailing possible issues iPhone users may encounter, this time revealing that the phone may experience a loss of signal, or reduced signal strength, if kept in a carrying case that uses magnets.

Last Modified on September 30, 2009, Support article HT2342 bears the title “iPhone: Signal or other interference while in carrying case.” It explains how the user must proceed in case of interference, bad signal, and so on.

“If iPhone is experiencing any signal strength, interference, or other issues while it is in a carrying case that uses magnetic clips to secure the phone try the following,” Apple says, proceeding with listing the instructions that apply to all three iPhone models available today.

- Remove iPhone from the carrying case. - Turn iPhone off and then on again. Press and hold the Sleep/Wake button on top of iPhone for a few seconds until a red slider appears, and then slide the slider. Then press and hold the Sleep/Wake button until the Apple logo appears. - Use iPhone to verify the issue is no longer present. - If the issue is no longer present, discontinue use of the case. - If the issues persist, contact AppleCare for service.

By doing a quick search on the web, Softpedia has discovered that several case / sleeve manufacturers have products that use magnets. For example, the product information for Sena’s dockable case for iPhone includes the following specs (highlight ours):

● Dock iPhone without Removing the Case; ● Answer iPhone without Removing the Case; ● Finest Italian Napa Leather; ● Slim Design; ● Innovative Magnetic Closure Design; ● Velvet Lining; ● Light and Rigid Protective Layer; ● Removable Belt Clip System – Use with or without Clip; ● iPhone Earphone and Speaker Openings; ● Camera Opening; ● Multi-Purpose Pocket; ● Proximity Sensor Opening; ● Charge Port Opening.
