How to unlock iPhone 4S Softbank with KingMobile

After so many attempts to unlock my iPhone 4S, after being twice a victim of scam from sites offering fake unlocks and after so much hacking with all the unlocks and jailbreaks techniques I found online, I finally found a way to do it. Thanks to my friend Birkir to point me in the right direction.

Based on KingMobile’s site, they also support iPhone 5/5S/6/6+. My experience is based only with the iPhone 4S, iOS 7, Softbank. I would like to know if someone else did it with a different version. Unfortunately it seems that this card cannot be used with an iPhone 4.

The procedure is pretty simple. Inside the package there is a small micro SIM frame with a chip that is the one making the magic. If you don’t have a micro SIM, you can request one or cut one yourself. That’s what I did. Just be pretty sure that you get the dimensions right.

Once you get the SIM in the frame, you have to put the SIM coming inside the envelop first. You will be asked to select your carrier. This is the carrier you want to unlock from. In my case it was Softbank. So select the old carrier, the one that is blocking your SIM.
Then follow the instructions. Once it’s accepted, a message saying that you selected a new carrier appears. After that accept and turn off your iPhone. Once you turned off your iPhone and the screen is black, QUICKLY replace the reset-SIM from KingMobile with your previously cut SIM card. This must be the new card you want to use. This is my girlfriend’s iPhone 4S by the way.

If you are not quick enough, you get this annoying message saying that the SIM is not valid. I repeated the operation again and it worked fine the next time.

Now you have your phone unlocked. Actually it’s not unlocked, technically the iPhone is still locked with Softbank and some menus in the settings still show stuff form Softbank remembering you that Masayoshi Son still owns your soul. Anyway the result is an unlocked iPhone as long as you use the KingMobile chip.

Few things you have to setup before start using your new “unlocked” iPhone.

      Set data roaming if you want to get your data connection enabled.
      Some carriers require you to setup your APN settings. That means that you have to enter manually the settings to connect with your carrier data network. In my case, it wasn’t necessary. I think that it depends on the carrier.
      I got some problems trying to call local numbers, and that was because I entered the number without the country code. It seems that the iPhone automatically puts a +81 (Japan code) in front of every number. To fix this is pretty easy. Just save your numbers with the corresponding country code. Even if you are calling a local number, add the +(country code).

Here you can find the instructions in English at KingMobile’s site.

The expert

This is a very well made video that shows a common situation faced, not only by engineers but, by almost everybody that has a logical and analytical mind when confronted by people that think they know your job better than you do. Enjoy :)

First impressions about Mavericks

I installed Mavericks over Mountain Lion on a MacBook Air early 2011. Let’s first start with the good stuff I found so far:

  1. More disk space. Before the installation I had 22GB free and now I have 34GB free. I have no idea what stuff was occupying 10GB of space, anyway it’s gone!
  2. Faster! Yes surprisingly it’s faster than Mountain Lion and Lion. I was a little bit afraid about the speed, specially after seeing how bad iOS 7 is doing on the iPhone 4 and the iPad 2.
  3. All my important apps work. So far I tried: TrueCrypt, VirtualBox, Chicken, Google Earth, LightRoom, Photoshop CS4, Illustrator CS4, AptanaStudio 3, Libre Office, TextWrangler, Audacity, VLC, JEDict, CyberDuck, Skype, go2Shell, Temperature Gauge.
  4. Leap Motion drivers work.
  5. Full screen works as indicated by Apple. I finally have my top bar enabled on the second monitor so I can now work full screen without sacrificing one monitor. I had one pretty bad issue that will be explained later in the post.
  6. The american voice Samantha is sexier than before.
  7. Disk utility didn’t crash until now…
  8. Battery had a better performance. I didn’t measure the charge time, but it discharges at a slower pace.

Bugs:

  1. I can’t rotate the second monitor. I used it at 90 degrees rotation but I can’t use it now. It was very handy specially to see the iPad/iPhone simulator working on it… Look at the image. This is ridiculous:
  2. Bug Rotation

  3. When I activated the second monitor in LightRoom it worked fine. But the second one’s top bar overlapped the maximized Lightroom’s second view. I can adjust that by making the second view a window but there should be no overlap of the content.
  4. bug full screen

  5. Sometimes you get something like this. I was in the launchpad and the app behind got an alert. The mouse pointer was operative with the launchpad icons but the content of the program overlapped the launchpad view. I had to click outside the window to get rid off the launchpad and respond to the message. If this is not a bug, it’s poor design

  7. In Lightroom I don’t get the right colors on the controls. Look at the image on the left is from Lightroom running on Mountain Lion and the right one on Mavericks. Don’t you see something is missing?
  8. mavericks lightroom bug

  9. I also had an issue with the keyboards. I have a Japanese keyboard which I use most of the time. I also installed an Italian and Spanish keyboard when I have to write in those languages. The problem is that the Japanese keyboard, when is set to Romaji, it means to write in roman characters, thinks that the previous used keyboard is the default romaji. So I ended up with a Spanish keyboard when I want to use the Japanese distribution. This didn’t happen with Mountain Lion. I fixed it by installing the US keyboard which maps the Japanese one. This is conceptually wrong, because based with the previous schema, the US keyboard should match an US keyboard distribution instead the Japanese one. Finally I gave up all the keyboards and I followed the advice of my friend @rcivit Now I use shortcuts to create characters like éáñ and so forth. Anyway I still have to install the US keyboard on a Japanese keyboard to have the right mapping…

So far so good, I won’t rollback to Mountain Lion mainly because Mavericks seems faster and more battery friendly. Anyway I wouldn’t use it for your production machine after at least 5 or 6 months.

Radioactive Lenses

I read this article in Petapixel about old radioactive lenses and I realized I have one of them!! So I gave it a try with a portable geiger counter I bought in Japan a couple of years ago.
I’m not an expert on the matter, anyway the normal safe level is 0.05μSv/h and the lens was 5.00μSv/h It’s not dangerous, but it was cool to see that indeed they made these lenses with some radioactive elements.

Based on this question posted on the website of the Health Physics Society, the element used was thorium to increase the index of refraction of the lenses. Based on the answer the use is safe and in their own words:

…the dose rate near the viewfinder of an old Pentax camera of mine (Super Takumar lens) is roughly 100 microrad per hour—approximately ten times background. In other words, looking through the viewfinder of this camera for one minute results in the same dose that I receive every ten minutes when not using it. I would have to hold this camera up to my eye for several million hours to exceed the threshold dose for cataracts…

I’m happy with this lens, in fact the optics of Takumar lenses is great! I use it with an adapter for Nikon to shot video and they work great.
Remember that the world is radioactive and it’s natural to live in a radioactive environment, as far as we don’t surpass certain limits. Anyway if you have a Takumar lens or any other old lenses that you feel afraid to use due their radioactive nature, please send them to me I will be more than happy to keep them safe :)

Interview to Davide Pasca an Indie Developer

I would like to introduce Davide Pasca, another indie developer, a good friend of mine and a real kick ass developer.

1. Davide, give us an intro about you.

I’m a guy with a passion for programming, especially computer graphics, but not necessarily.
I started early as a programmer in Italy, working as a software developer on Mac, while cultivating my passion for graphics and video games on the Amiga first and on PC later on.
I eventually moved to the US in 1995 for my first real job in the game industry. Six years later I moved to Japan, in Tokyo, where I’ve been for about eleven years now.

2. What made you take the decision to be an indie developer?
