iPhone learned to forget

Recently there has been a smaller scandal about re-sold iPhones, as nothing could have been securely erased from their huge memory, as the device called a smartphone by Apple, accepts no application to be installed on it that could securely erase its memory. Since then Apple has announced its new software, iPhone 2.0, which on one hand is open for applications and on the other hand it has data destruction feature by default. The process is very simple, as the software overwrites the whole memory with randomly generated datam thus making data restoration completely impossible. This process, due to the huge 8 or 16 GB of memory, is quite long, as you can see on the picture it can take up to an hour.
