German court tosses Samsung's 3G-related lawsuit against Apple
On Friday German Judge Andreas Voss rejected Samsung's numerous lawsuits against Apple in Germany, accusing the iPhone maker of violating a patent related to 3G/UMTS wireless communications. The lawsuit included 7 different patents; six of these patents are tied up in four other lawsuits. Though Voss did not provide a reasoning for his pronouncement, if he had determined that Samsung's 3G patent was invalid, the outcome of the lawsuit would have been a stay rather than a rejection.
"There are two reasonably likely possibilities: either Apple's products weren't deemed to infringe on the patent in a technical sense or the court believes Samsung's rights are exhausted and Apple has, by extension, a technical license," Mueller wrote.

Consumer Reports Criticized Verizon iPhone 4
New post on Consumer Reports' blog written by Mike Gikas and Paul Reynolds reveals that the company thinks Verizon iPhone 4 will have a short life as soon it will "be replaced by a newer, cooler version more quickly than is customary even for the die-young life expectancy of most smart phones."
It is true that Apple made the CDMA-enabled iPhone a mid-year carrier expansion, and most observers expect new iPhone 5 will not replace its less than 6-month old predecessor as at launch it will support only GSM / UMTS technologies. However, Apple's rivals do not propose any product cycles anyway and release new handsets every few months, so the position of Consumer Reports looks pretty inconsistent.

Apple asked FCC not to show iPhone 4 details for 45 days
On June, 4 Apple sent a letter to the FCC (Federal Communications Commission) with request to keep new iPhone’s photos and any information about it in secret for forty five days.
Though this is a standard practice for Apple, the situation looks pretty strange as the device’s internals had been already revealed with numerous prototype leaks. But Patently Apple, the company that obtained and published the letter, found the explanation in the document itself:
“Although Apple has begun to market the device publicly, these documents reveal technical and design information that has not yet been publicly disclosed in such marketing and that is protected by Apple as confidential and proprietary secrets”.
AppleInsider created a list of new iPhone’s technical details and features that Apple may want to keep in secret for a while. It includes new features of A4 SoC, details of new frame antenna, new cellular radio support for pentaband UMTS (850/900/1700/1900/2100MHz) 3G bands, details related to possible support of T-Mobile (AWS UMTS IV band) and Verizon/Sprint (CDMA/EVDO) networks.
