Yesterday Apple introduced new service called iCloud. US users can try it today using iOS 4.3.3 and iTunes 10.3. To understand what is iCloud, what is it for and how can be used, we recommend to read official Apple text about iCloud.

- The new Notification Center will aggregate all notifications that will appear at the top of the screen and will be less obtrusive overall.
- iOS 5 will be "PC free" , so a new device and iOS updates can be activated over the air.
- Tunes library can be also synchronized wirelessly via Wi-Fi.
- AirPlay Mirroring will also be possible to wirelessly mirror an iPad's display to a television connected to an AppleTV.
- Twitter will be integrated into iOS and Contacts can be updated automatically.
9to5mac reports that Apple starts officially selling the iPad 2 in Russia and Ukraine this Friday, May 27. That’s the same day carrier Aircel will start offering the iPhone 4 in India, in what it looks like a day focused around international releases ahead of the WWDC. The Russian iPad 2 sales will begin this Friday through retail chain Re:Store, with MediaMarkt, Beliy Veter Cifrovoi, ION, Technosila and Eldorado also looking to jump on board for the May 27 rollout. Retailers are expecting “unprecedented demand” for the iPad 2, which doesn’t surprise considering the device’s popularity and the lack of Apple’s retail presence in Russia.
It seems that many users are experiencing WiFi connectivity issues on devices running the latest iOS 4.3.3. These issues are nothing new to iOS but this time it appears they’re affecting iPhone and iPod touch models as well. A device fails to connect to a network or is unable to navigate; the WiFi icon doesn’t appear in the statusbar even if the device is actually connected; the device randomly disconnects from a network.
HardMac reports that that the latest iMac family released this week support up to 450 Mbit/sec Wi-Fi. Apple first brought the 450Mbps WiFi features in the 2011 MacBook Pro family, but they haven’t been actively advertising it. Apple changed their Airport card and also installed 3 antennas (instead of 2 before), something indispensable to be able simultaneously to use 3 channels of 150 Mbits/s. Each antenna is capable of a data rate of 150 Mbit/sec. Combined, the three antennas achieve the 450 Mbit/sec speeds using the multiple-input/multiple-output (MIMO) wireless standard.
As noted by AppleInsider, the newest iMacs and MacBook Pros must be running a developer build of Lion to take advantage of the 450 Mbit/sec speeds. And MacRumors notes that in order to actually take advantage of the 450 Mbit/sec speed, you'll need to have a compatible wireless router, such as the latest AirPort Extreme or TimeCapsule.
Multiple sources say the new feature will debut in iOS 5, meaning iOS 5 will not come over-the-air but following point updates to it will. Just like tethering in iOS 3, Apple has the technology but cannot just unleash it everywhere. Apple and Verizon Wireless are said to have been in talks over these wireless software updates since early this year. Sources could not comment on whether or not Apple is negotiating similar deals with AT&T or international iPhone carriers.

It was also found that the device collects location data using Wi-Fi access points and cellphone towers (triangulation method). However, this information is not being transmitted to Apple.

iFixit announced that they completed the teardowns of the GSM and CDMA models of iPad 2. Wi-Fi version of the iPad 2 was torn down on launch day. The GSM model has the micro-SIM card slot along the upper left edge to provide the device with subscriber information. On the CDMA version such information stores directly on the WWAN board inside. The CDMA iPad offer slightly different antenna configurations, it has an additional antenna and an integrated GPS receiver. What’s really curious is that the 3G version of iPad 2 has the older Infineon 337Se833 baseband chip rather than a dual-mode Gobi chip found inside the CDMA iPad 2. Maybe it was a supply issue or an engineering decision designed to cut costs a bit.
Apple seems really dislike everything that helps users to jailbreak their devices. This time Apple blocked access to the Cydia website via Wi-Fi network in Apple retail stores. If you try accessing Cydia on a device connected to one of Apple’s Wi-Fi hotspots, you’ll be surprised to see Apple’s website load instead. As far as we remember, last year federal regulators said that it was no longer illegal to hack or jailbreak an iPhone. However, Apple doesn’t care about that and continues its “war” with jailbroken devices.
iPad 2 microphones: 3G (top) vs. Wi-Fi (bottom)
iLounge found out that the microphones on Wi-Fi and 3G models of iPad 2 have differences in quality of sound. The best sound quality was demonstrated by the Wi-Fi model. It might be caused by the fact that the mic on the Wi-Fi model is on an aluminum surface while on 3G is on the black plastic. The differences are most noticeable when the iPad is held facing the user, for example, when using FaceTime or other video applications.
Perhaps due to this change in materials, the Wi-Fi model offers markedly cleaner audio than that of the 3G, which sounds slightly muffled and echo-prone as a result. Curiously, we found the GSM 3G model's audio to be slightly preferable to that of the CDMA model, which seemed to suffer the issues more severely.
In the previous model of iPad the microphone located next to the headphone jack on the top edge but in iPad 2 Apple decided to place it in the center. Though, it seems that such change does Apple more harm than good.
Staff brought out surge protectors and extension cords with 10s of iOS device adapters so people could charge their phones & pads and contact their loved ones," the manager wrote, noting that the Apple retail stores are some of the only locations to offer free Wi-Fi in Japan. "Even after we finally had to close 10pm, crowds of people huddled in front of our stores to use the wifi into the night, as it was still the only way to get access to the outside world.
iFixit, as usual, prefers not to waste time and has already teardown newly released iPad 2 16 GB Wi-Fi model. The iPad 2 wasn’t easy to open because of tons of glue (not screws) used to seal it. The iPad 2 is very densely packed and has less empty space inside the body comparing with the original iPad. Here are the initials found inside:
Yesterday ChangeWave revealed the results of another survey, which shows that 82% of future tablet owners would prefer to buy an iPad instead of its competitors, namely Motorola Xoom and RIM Playbook.
3,091 consumers were asked in February what tablet would they like to buy and only 4% and 3% would choose Xoom and PlayBook respectively. Another 3% would stick with Samsung Galaxy Tab.
