Apple Updated Security of Iphone

Labels:


After the release of Nokia N96,5800 XpressMusic the position of Apple Iphone in the market is very bad.So apple is changing their policies and they are planing to update their models.Among the many improvements to the iPhone with the 2.1 software update posted on Friday are changes meant to enhance security on the device. Apple has provided details about what's changed. All of the changes affect security issues noted for iPhone 2.0 through 2.0.2 software releases. None of the problems affect iPhone software prior to 2.0.

Changes have also been made to improve security with the iPhone's network connectivity. mDNSResponder has been updated to reduce susceptibility to DNS cache poisoning. TCP initial sequence numbers are now randomly generated, to thwart remote attackers from spoofing TCP connections.

The Passcode Lock feature is used to keep users from making accessing the iPhone without entering a multi-digit code. That feature could be thwarted thanks to an exploit involving the handling of emergency calls; that has been corrected.
WebKit on the iPhone has also been updated to address an issue associated with the handling of Cascading Style Sheet (CSS) import statements. Document reference handling has been improved to prevent this problem from occurring.

Apple Inc. updated the software that runs its iPhones on Friday in hopes of decreasing dropped calls, improving battery life and cutting the time it takes to synchronize the device with a computer.

Apple also said the new update "improved accuracy of the 3G signal strength display" — meaning the phone would show more "bars" on the connection meter. However, the quality of the connection was not necessarily affected by the update.

Nokia N95 vs. Sony Ericsson K850i

Labels:













K850i
good: Dedicated camera controls; microSD and Memory Stick Micro compatibility; Xenon flash and LED light; Bluetooth stereo; HSDPA connectivity.
bad: Glossy surface attracts fingerprints; tiny buttons may not appeal to some.

  • The K850i Cyber-shot is one of the best camera-phones available in the market right now, thanks to its dedicated controls, good performance and natural-looking images.
The design concept of the K850i is modeled mostly like after today's digital cameras. Taking a page out of the Sony Cyber-shot book, the K850i sports a slider switch that toggles between the shooting modes and playback function. Previously, we had to access the onscreen menu to change from stills to motion images. With this new hardware switch, we find toggling between shooting modes a lot easier.

N95
good: HSDPA; Wi-Fi; onboard GPS; 5-megapixel camera with Carl Zeiss lens; 3.5mm audio jack; mini-USB connector.
bad: Build quality doesn't justify the premium price; poor battery life; sluggish performance when multiple applications are running; premium price.
  • There's no doubt that the Nokia N95 is one of the most full-featured smart phones available right now, but its poor battery life could very well be its Achilles' heel.
The Nokia N95 is one smart phone that just doesn't measure up, especially if you consider all the features in its minute size. Although the N95's footprint is only slightly larger than a credit card, it is thick on the side. In hand, the unit feels surprisingly light. The soft-touch finish on the back is a pleasure to hold, though the plasticky build of the body gives it a less than solid feel.
