Meanwhile, the struggle for the frequency, suitable for the construction of LTE-networks, a new level. After the letters to officials of various ranks with requests to distribute the frequencies on the basis of open competition from the operator's manual "big three", began arriving requests from shareholders cellular operators. So, the day before the owner of AFK Sistema (owns MTS), Vladimir Yevtushenkov and "Alpha groups" (owned by VimpelCom with Telenor), Mikhail Fridman met with First Deputy Prime Minister Igor Shuvalov to persuade the Government not to give up without contest the most suitable for network construction of the fourth generation communication technology LTE frequency. According to the shareholders of the big three, these frequencies - a limited resource, and therefore, by law they must be put up for competition.

Tablet PC iPad is a fairly balanced device, but the development of modern video technology may require a more serious mobile computer hardware capacity and longer battery life. Perhaps that is why the new model iPad will have 512 MB of RAM and run on the processor ARM Cortex A9, which has a great potential. Want to rumors about the 7-inch plate (sometimes even referred IPS-LCD screen with a resolution of 1024x768 pixels), but there is still no certainty.

Once removed the "twins" the final figure dropped to 600 million units. Then remove from the calculation of the book with the same content but different names, maps, data on T-shirts, audio and video recordings, and periodicals that go often - and got the final 129 million "and a little bit."
Google Books project was launched in 2004. Currently, the Google Books catalog has about 10 million titles.

Google knows this statistic and do everything possible to promote his store Android applications among software developers for the iPhone. The company sent many of them free smartphones Nexus One, in order to induce them to rewrite their applications for Android. The new utility Android App Inventor will also attract new developers: it helps to create simple programs without having to learn code.
Despite the current dominance of the App Store on the market for mobile applications, Mr. Don Keene sure that Android will continue to reduce the distance.
