iPad 3G ripped apart by Gizmodo

01/05/2010

We’ve seen its communications board before, but now the entire iPad 3G has been torn open and had its parts analyzed. Here’s what makes it different from a Wi-Fi-only iPad according to the guys at iFixit:

* The immediate visible difference is the inclusion of a black plastic RF window on top of the iPad for better antenna reception.

* The black RF window significantly changes the opening procedure. You cannot start separating the display using the notches on the top (à la Wi-Fi version), since that will undoubtedly break the RF window. You have to start from the right side and gingerly proceed to the top and bottom of the iPad.

* There are actually FIVE antennas in this iPad: Two antennas handle the cell reception — one is in the RF window on top, the other attaches to the LCD frame. A single GPS antenna is also housed in the RF window on top. Just like the iPad Wi-Fi, there are two antennas that handle Wi-Fi / Bluetooth connectivity, one in the Apple logo and another to the left of the dock connector.

* You heard that right, folks: Apple looks to be using the entire LCD frame as an antenna!

* Who would’ve thought: Apple uses the same 3G baseband processor in both the iPhone 3GS and the iPad 3G.

* The baseband processor in question is the Infineon 337S3754 PMB 8878 X-Gold IC. It was actually white-labeled on the production unit, but with enough sleuthing we were able to confirm its true identity.

* The iPad 3G has a Broadcom BCM4750UBG Single-Chip AGPS Solution, whereas the iPhone 3GS uses an Infineon Hammerhead II package. Big win for Broadcom!

* Apple did not change any major suppliers between manufacturing the pre-production unit they provided the FCC and their final production run.

iPhone OS 4.0 is now official with over 100 new features

10/04/2010

The sneak peak event on iPhone OS 4.0 is now over. Steve Jobs was on stage and he promised tons of new stuff for the next-gen iPhone OS. There’s multi-tasking, app folders, social gaming plus so much more.

As you’ll see from this slide there are many new interesting features, but in their presentation Apple decided to concentrate on the “7 tentpole ones” – as they call them.

iPhone OS 4.0

1. Multi-tasking

Multi-tasking on the iPhone – well, how about that! It took them 3 years and three (almost four) generations of iPhones to come to that. They know they’re late but Steve Jobs is promising their implementation is the best so far. And multi-tasking won’t slow down or drain the battery.

The way they do it on the front-end is simple. Double tap the hardware key and the task switcher appears as a dock below whatever app is running. Oops, there goes our only shortcut key.

Multitasking

On the back-end things are different. Instead of keeping all apps running in the background, they allow apps that need multi-tasking access to 7 background services. So it’s actually the services that run in the background – not the actual apps.

The background services seem more than enough to cater for the needs of various applications. They include background audio, VoIP, background location, push notifications, newly implemented local notifications, task completion and fast app switching service that takes care of returning apps to you in the way you left them even though they DIDN’T actually run in-between.

The new local notifications will allow scheduled alerts such as one from a To-Do app. Finally!

2. Folders

Next up are folders. But not the file system variety. No, sir! You’re not getting a file manager on the iPhone just yet.

Folders

The new iPhone Folders will do what the Categories app does for jailbroken phones. It allows grouping of applications into meaningful categories (such as Zombie Games, for instance) so you don’t have to flick through all your homescreens for some blood-splatting action.

3. Improved email

The Email app on the iPhone now will offer a common inbox for all email accounts setup on the phone. No more flicking back and forth. And corporate users will be glad they can have more than one Exchange account setup.

Improved email

Fast inbox switching is also available now along with threaded email conversations. And you can also open attachments with an application you’ve downloaded from the AppStore.

4. iBooks

The iBooks e-book reader you’ve probably seen demoed on the iPad will now be available to the iPhone as well along with the iBookStore and free copy of Winnie The Pooh (not kidding!).

5. New features for enterprise

Targeting the enterprise clients, Apple has introduced a bunch of new stuff such as better data protection (email encryption with your PIN code), Exchange Server 2010 support, SSL VPN support, mobile device management and wireless corporate app distribution.

6. Game center

With iPhone OS 4.0 gaming will get a new social networking aspect bringing it up to speed to the Windows Phone 7’s Xbox Live interconnectivity.

With the new Game center you’ll be able to invite friends for online multiplay, you’ll be able to post scores in Leaderboards and unlock Achievements.

7. iAd mobile advertising solution

The final “tentpole” of the new iPhone OS is a new mobile advertising system for the iPhone, iPad and the iPod touch that called iAd.

iAd will allows developers to integrate ads into their apps so that they can possibly release free, ad-sponsored versions of their apps.

With iAd users will be able to click on advertisements and check them out (even video content) from within the application they originally saw them in.

Apple will be selling the iAds and will host them as well. In return they’ll be getting 40% of what the advertiser is paying. Developers get the rest.

Misc stuff

As of iPhone OS 4.0, users will be able to add a wallpaper image to the springboard itself. It’s something jailbroken iPhones have had for years, but it’s nice to have it out of the box as they do on the iPad.

As we already said, there are lots of other new things such as Bluetooth keyboard support, search in SMS/MMS, tap-to-focus in video recording, Places in photos sourced from the geotagging information, web search suggestions, recent web searches list, photo rotation, workout uploads to Nike+, gift apps, etc.

Availability

The new iPhone OS 4.0 will be available this summer (along with the new iPhone we presume) but they’re issuing a developer’s preview today so we should hear a lot more about those new features in detail in the coming months.

The iPhone OS 4.0 will be available to the iPhone 3G and 3GS as an update. However many of the new features, INCLUDING multi-tasking won’t work on the iPhone 3G. There’s no word about the iPhone 2G yet.

And since the iPad is a hot topic right now – yes, it’s also getting an update to iPhone OS 4.0 – however later on – in the fall.

Early iPad User Complaints: Weak Wi-Fi, Charging Issues

06/04/2010

Straight from MacRumors.com:

With the iPad’s U.S. release to the masses on Saturday, several complaints have arisen from users experiencing difficulties with their new devices. Two of the highest-profile complaints in the early days have been weak Wi-Fi signals and confusion over USB charging of the device.

Apple’s discussion forums have received a significant amount of activity regarding the Wi-Fi issue, which typically results in users receiving a significantly lower signal than computers or iPhones held in the same location relative to the access point. The reduced signal is resulting in slower performance and smaller range for many of these users. Users have also reported seeing significant fluctuations in signal.

Speculation has centered around the iPad’s external shell and power-saving measures as possible reasons for the Wi-Fi performance issues. While Apple has strategically placed the iPad’s Wi-Fi antennas to provide optimal reception, the device’s aluminum rear enclosure almost certainly shields reception to some degree. Additionally, some users have wondered whether Apple is supplying reduced power to the Wi-Fi hardware as part of its power-saving techniques that have enabled the iPad to meet or exceed its stated 10-hour battery life in many cases. Regardless of the cause, Apple has yet to comment on the Wi-Fi situation, although it has in the past quietly addressed similar issues through software updates when possible.

A second issue experienced by users has been difficulty with charging the iPad via USB. A number of users have discovered that their iPads refuse to charge when connected to USB ports on some computers, an issue that Apple has stated is due to the required power draw for the device. In a support document posted on the issue, Apple recommends that users charge their iPads by using either the included power outlet adapter or high-power USB 2.0 ports.

When attached to a computer via a standard USB port (most PCs or older Mac computers) iPad will charge, but only when it’s in sleep mode. Make sure your computer is on while charging iPad via USB. If iPad is connected to a computer that’s turned off or is in sleep or standby mode, the iPad battery will continue to drain.

The iPad’s charging demand stems from its large battery that drives a significantly hungrier device than most mobile handhelds users are accustomed to charging via USB. Consequently, lower-power USB ports have difficulty keeping up with the iPad’s draw, especially when the device is not in sleep mode. With the iPad’s U.S. release to the masses on Saturday, several complaints have arisen from users experiencing difficulties with their new devices.
