Apple is insistent on closing all doors for rival Samsung's Galaxy Tab 10.1 to enter Australia - even through online retailers.

To close the backdoor used by Aussie techies, Apple wrote a letter to eTail Solutions to request the Queensland e-commerce provider to comply with the injunction issued by Australian Federal Court Judge Annabelle Bennett.

"They've sent one to eTail Solutions and we've passed it on to the Hong Kong owners of MobiCity. However, an injunction would have to take place within Hong Kong for it to have any effect on them," eTail Solution Marketing Manager Alistair Eldred told The Australian.

MobiCity is one of the online retailers that offer the Galaxy Tab 10.1. The others that continue to circumvent the ban are eBay, Expansys, Techrific and dMavo, which get their stocks of the Samsung-made tablet computer from other countries such as Hong Kong.

dMavo Managing Director Wojtek Czarnocki said he expects to get a similar letter from Apple although he has not received one yet.

"We'd be silly not to expect them to take a bit of an interest in us. We're keeping our eyes and ears open but at this stage we haven't been contacted by Apple," Mr Czarnocki said.

"Samsung Electronics Australia is not able to comment on the extent of the Federal Court's injunction of the Samsung Galaxy Tab 10.1, only that it will adhere to the ruling while an appeal is being pursued," a Samsung spokeswoman said.

Micro retailers such as OzDigital, Austnetauction, Eclipse Mint and au-azmobile have joined the action and also sell the Galaxy Tab 10.1 from eBay with price ranging from $500 to $800.

In contrast, Apple's iPad 2 retails from $579 to $949.

As the competition between the erstwhile business partners worsens, the legal battle between Apple and Samsung is expected to include as many countries and devices as possible since the Cupertino, California-based company founded by Steve Jobs appears to be carrying out the threat made by Mr Jobs against Android.

In a book on Mr Jobs, author Walter Isaacson quoted the Apple founder as saying that he would destroy Android, the OS used by the Samsung smartphones and tablet computers, because it is a stolen product. He promised to go on a thermonuclear war against the Android.

Another Galaxy device likely to be hit by future lawsuits by Apple against Samsung would be the Galaxy Tab 7.0 Plus which is slated for a U.S. launch on November 13. Again, the price point would surely cause Apple jitters since the new model will retail for $399.99 or $100 less than the iPad.

The Galaxy Tab 7.0 Plus uses Android 3.2 or the Honeycomb OS, which is an upgrade from the previous version's Android 2.2 or Froyo OS. It will also feature the Touchwiz interface and a sticky mini app tray that could be pulled up from any screen and used to load various preset apps.

Galaxy Tab 7.0 Plus would have a 1.2-Ghz dual-core processor and the seven-inch screen will have a 1,024 x 600 resolution that supports four-way rotation made possible by the tablet's gyroscope and accelerometer.

However, the Nov. 13 roll-out is just for the 16-gigabyte version of the Galaxy Tab 7.0 Plus. There is no word yet from Samsung about the 32-GB version.
