Although Macs seem to be the dream-computers, with no viruses and no frozen screen, the same cannot be said about the accessories you receive when buying an iPhone 3G.

The phones’ USB power adapters can cause electric shocks, according to the company. The blades of the adaptor can apparently snap off and remain inserted into the electrical socket, as reported by Apple customers. Fortunately, no injuries have been reported so far.

Because Customer Care is a cardinal priority for Apple, the company pulled all the packages that include these adapters and replaced them with safety-improved ones.

The adapters are similar, the only differences being a green dot on the bottom, to make them distinguishable from the old one and the shape of the blades: while the ends of the original blades were square, the new ones are pointier.

The company has also offered to replace the already purchased adapters, free of charge. These adapters can be replaced either via the Web, which takes them about three weeks to arrive, or at any local Apple retail store, starting with the 10th of October.

Apple reported they have sold about a million units of the iPhone 3G worldwide during their first weekend of sales, in July, reports ChannelWeb.

The only foreseeable problem is that Apple customers are advised to stop charging their phones until the new adapters are in their possession and use the classic USB chargers on their PCs or Macs instead.

Although the costs of this replacement frenzy will be high, Apple is satisfied to guarantee their customers’ safety.
