iPhone 4 Camera Spec

I didn't post any photography related topics in the past 2 weeks and was busy with iPhone 4 & iOS4. I promise I will post more photography info right after this. By thy way, this is kinda related. Following is the iPhone 4 back camera spec in case you want to know.

  • 5.0 Mpixels (2592 x 1936)

  • 1/3.2" back-illuminated CMOS sensor

  • 4:3 aspect ratio

  • 35 mm film camera crop factor: 7.64

  • Low ISO 80 (or better)

  • 3.85 mm lens focal length

  • f/2.8 lens aperture

  • Autofocus: tap to focus

The senors size is almost as big as the ones on a low end P&S and it is a back-illuminated CMOS sensor which helps with lowlight conditions. With this lens and sensor size, it corresponds to 35mm film camera equivalent lens of 30mm with f22.

iPhone 4 unboxing side by side with my 3Gs

Just a quick unboxing video with my 3Gs on the side. Just in case you wanna watch it.

p.s. the iPhone case you saw in the video you can buy from here.

Macally iPad Case unboxing

Since the Apple iPad Case is in shortage at this moment, I am going to show you an alternative solution from Macally. The above video shows you the unboxing of the case and side by side comparison with the Apple original.

What I like
the Color
the better fold angle (horizontally or vertically) for viewing video or typing

What I don't like
the front cover is too soft
get dirty easily due to its microfiber material
not able to cover the edges of the iPad 100%, it only covers the 4 corners

If you can't wait for the original iPad case from Apple, you can get Macally for $40 Shipped here

p.s. I am really sorry I keep pronouncing Ma"cathy" instead of Ma"cally" in the video.

iOS4 Push Notification fix (for Unlocked Phone)

People talk about unlocking iOS4 on iPhone 3G/3Gs and a lot of sites provided instruction already. But I would like to show you how to fix the push notification if it fails after the unlock.

Following are the directions for how to fix your unlocked iPhone.

1, Make sure you’ve jailbroken and unlocked your iPhone 3G/3Gs with iOS 4.
2, Make sure you dont have any app which uses push function on your iPhone. If yes, remove all of them first.
3, Open up Cydia, and add this address to the sources: as above
4, Once Cydia is done updating, go to the search field and type in: Push Doctor. Tap it, and then press install.
5, Wait until complete download and install.
6, Restart your iPhone.
7, After restarting, you may install any app which support Push function. e.g. Meebo
8, Run the installed app and it will tell you to enable Push Notification by Tapping Settings.
9, Tap Setting and enable it.

Push Notification should work by now.

Easier way to check iPhone 4 Upgrade Eligibility

More than one friend asked me how to check if they are able to get the iPhone upgrade with discounted offer. If you are a current At&t iPhone customer, there is a easier way to check if your line is eligible or when it will be eligible for an iPhone 4 upgrade, which means you can pay $199 for 16GB or $299 for 32GB iPhone4.

Step 1,  try to call *639# from the phone screen

Step 2, press Dismiss while you waiting for At&t server's respond

You will get a message reply from At&t in less than 2 mins saying whether you are eligible or not.  The following image shows you are not eligible now, it tell you the date (black out area) when it will be eligible.

Please note that you will be able to pay $200 more for an early upgrade even if you are not eligible at this moment.

Be Awared if you planning to unlock iPhone 4

SIM CardlengthWidthThick

Above SIM card info. is for your reference if you are planning to unlock iPhone 4 and use it with another carrier. Currently, T-mobile does not offer Micro-SIM cards which is required by iPhone 4 (also iPad). Even when there is a  solution to unlock iPhone 4 in the near future, you will need to be prepared to cut your SIM card base on the above spec. of Micro-SIM card.  There is proof on the  internet that iPad is able to use the EDGE service from T-mobile while there is no way to use the 3G service due to the different frequency from AT&T

T-Mobile USA Network
AT&T USA Network
iPhone 4 Supported Frequency
EDGEGSM/EDGE (850, 900, 1800, 1900 MHz)
3GUMTS/HSDPA/HSUPA (850, 900, 1900, 2100 MHz)

Just in case you still want to do it and you know what your are doing, You can try to use T-mobile EDGE APN Setting as followings.

As you can see from the screen capture above, iPhone ship date keeps pushing back. If you are planning to get one, order it now. Rumors say, the White iPhone will be available for pre-order before 6/24, however, don't put too much hope the white one will  ship before 7/14.

I am using Google Chrome

Needless to say, the most frequently used program on your computer is the Internet Browser. Since this browsing experience is related to user behavior and its pretty hard to change for normal people, you may need to think twice before selecting which browser program to use. I believe most of you are using Internet Explorer while some people using Firefox and maybe its time for a change.

Why I don't use IE
I kinda stopped using IE in the pass 3-4 years beside at work. IE get attacked by malicious websites easily. Some attack utilizes IE drag-and-drop & ActiveX features to copy executable file to a user's Startup folder, from which it would execute the next time the user logged on. (That's one of the major reason your computer gets infected by virus after browsing unsafe websites). In short, IE is tied in so close to the operation system it will have higher security risk than the other browsers.

Why I pick Chrome vs others
Chrome focus on S.S.S. Which means Speed, Simplicity, Security. I am not going into detail to compare the different browser's performance here but Google Chrome did make it very clear of their goals for you and you can feel it from their latest version 5. Followings are the reason I am using Chrome now.

  • Mulitingual Web Surfing

  • Cross Plathfrom (Windows, MAC, Linux)

  • HTML5 Support

  • Bookmark & Preference Sync

  • Google Extensions

  • Address Bar (Search & Navigate from the same Box)

Other browsers may have similar functions that I mentioned above. However, Google Chrome has them all in one package. Also, I believe Google will take Chrome as the first step of Cloud Computing and we will see a more clearer picture when Chrome OS is released later this year. If you haven't tried Chrome yet, download from the link here and give it a try. After all, if you don't like it, you can always uninstall it very easily.

After iPad Jailbreak, What's Next?

The Story

After my "iPad Jailbreak Software has been released w/Download Link" post was up, friends keep asking me what to do next. Most of them would like to achieve the goal of installing paid apps for free. I am going to post the directions here but I am not responsible for any illegal actions.

The Solution

If you watch the video of my previous post and follow them step by step, you should be able to see Cydia on your iPad. Follow the additional steps to install AppSync 3.2 and your iPad will allow you to install downloaded apps.

  1. Open Cydia (it may ask you to update, just accept everything)

  2. Click Manage

  3. Click Sources

  4. Click Edit

  5. Click Add

  6. type

  7. Click Add Source (You can add "" as well in cause is offline)

  8. After Add Source, your Cydia will try to update all the available software list, wait until it is done.

  9. Now Click Search and search for AppSync 3.2 (if you are doing this for iPhone, get 3.1)

  10. Download it and let the iPad install the software itself.

Now, your iPad is ready to install downloaded apps.

Following is a website which has tons of apps for you to download (Just for your reference). Download the ipa files from your desktop, double click on it and have iTunes install it to your iPad. Remember, If you like the App, you should buy it.

Update:  Just in case you would like to install cracked apps directly from internet, search and download "Install0us" from Cydia as well.
