Downgrade iPhone 3.1 to 3.0For anyone who have accidentally upgraded to iPhone OS 3.1 and would like to downgrade back to OS 3.0, you can follow this guide for the downgrade. This guide is written for iPhone 2G and 3G only. It will not work for iPhone 3GS.

By downgrading your iPhone 2G/3G from OS 3.1 to 3.0, you can use redsn0w to jailbreak it again. But for iPhone 3G user, while you can jailbreak your iPhone, ultrasn0w will not work for you as iPhone OS 3.1 has upgraded the baseband.

Apple Releases iPhone 3.0.1 to Fix SMS Vulnerability

August 1, 2009 — by Simon Ng3


Apple has released iPhone OS 3.0.1, which is a minor update for iPhone 3.0, to fix SMS vulnerability, after security experts demonstrated the exploit at a top security conference (known as Black Hat).

According to New York Times, the SMS exploit was discovered by two security researchers – Collin Mulliner and Charlie Miller. As claimed, the vulnerability will allow hackers to take over any iPhone and gain complete control with a simple SMS.

On Thursday, they demonstrated in a security conference and showed how they can take advantage of this exploit to hijack iPhone and gain complete control of it including making phone calls, visiting websites, taking photos with camera and even revealing personal information.

What’s more is that hackers can make use of the hijacked iPhone to send malicious SMS to other iPhones. So, theoretically, hackers can take over all iPhone in the world.


iPhone 3.0 Tip: Improved Stock App with News and Landscape Support

July 27, 2009 — by Simon Ng1


You probably have upgraded to iPhone 3.0. But do you know the Stock application has been improved with minor tweaks? I guess not every iPhone user notice the changes.

The Stock app is a very simple app that lets you keep track of stock price of your portfolio. Before the release of iPhone 3.0 OS, it only shows the delayed stock quote, as well as, a simple chart of historical stock price. On iPhone 3.0, Apple improves the Stock app with a couple of features:

1. News & Stock Summary
2. Landscape mode support

News & Stock Summary

When you first launch Stock app, the look & feel doesn’t change much. But try to drag the stock chart from right to left and you can see the latest news related to the stock. On the other hand, flick the chart from left to right, you can find the stock summary.


Upload Video from iPhone 3GS to Facebook, Blogspot & YouTube with Video Uploader

July 20, 2009 — by Simon Ng31


With the debut of iPhone 3GS, Apple finally brings video to iPhone. Now, in the Camera application, you can easily toggle between video and still-picture mode to capture high-quality video. It also comes with sharing feature to let you send video clips via email or upload them directly to YouTube.

But, probably that’s not enough for some iPhone users (including me). How about Facebook support? You may just capture some really fun videos and wanna share them with your friends on Facebook while you’re still on-the-go. How can you share video to Facebook? Or you own a blog on How can you upload the video clips directly to Blogspot for your blog post?

CirclePix has released an iPhone app called Video Uploader to address this need. The application allows you to upload video clips to Facebook, blogspot, as well as YouTube. The interface of the app is pretty simple and intuitive. It doesn’t load with any fancy features but only focus on video upload.

Tips & How-to

iPhone 3.0 Tip: Just Shake and Undo Typing

July 18, 2009 — by Simon Ng4


As claimed, Apple brings us over 100 features in iPhone 3.0 OS. But not all features are as prominent as Copy & Paste or Voice Memo. Some features are not explicitly mentioned by Apple and you’ll have to discover by yourself. Here is one:

Simply shake your iPhone and Undo the typing

It’s a very simple feature and makes a very good use of iPhone built-in accelerometer. Say, you just type a sentence in Notes. You think it’s not good enough and want to start over again. In the past, you may use the backspace button to erase the sentence. Now, on iPhone 3.0, you can simply shake the iPhone and undo the typing.


iPhone 3.0 Tip: How to Forward SMS and Delete Individual Message

July 16, 2009 — by Simon Ng0


Prior to iPhone OS 3.0, you are not allowed to forward a text message (or SMS). It’s really ridiculous that such basic feature, which is available on most mobile phones, cannot be found on iPhone. Finally, the latest version of iPhone OS brings you the ability to forward SMS, as well as, deleting an individual text message.

Though it takes Apple nearly two years to bring us this feature, the interface is well-thought and intuitive.

Let’s see how you can forward SMS and delete individual text message on iPhone 3.0.

First, launch “Messages” application and tap on any of the text messages. Next, tap on the “Edit” button on the top-right corner and iPhone will show you an interface to let you select individual message.


How to Force Quit an Application for iPhone 3.0

July 11, 2009 — by Simon Ng9

Normally, you can force quit an iPhone application by pressing and holding down the HOME button for around 6-8 seconds in firmware 2.2 or lower. But as Apple released the iPhone 3.0 OS, this method does no longer work. The HOME button shortcut is now preserved for invoking Voice Control, which is a new feature introduced in iPhone 3GS.

So, how can you force quit an application for iPhone 3.0?

July 10, 2009 — by Simon Ng17


One of the popular questions that I have been asked is how you can share contact with others on iPhone.

Three months ago, I have posted 3 great ways to forward a contact to your friends or co-workers. They should work for you but they’re not perfect. And, the solutions depend on 3rd party applications.

With the release of iPhone 3.0, Apple finally built this feature into iPhone and allows you to share contacts with others via MMS (not available for all carriers) or email natively.

New Features for the Upcoming iPhone 3.1 OS

July 2, 2009 — by Simon Ng0

Though Apple does not disclose any details about the iPhone 3.1 beta update, some iPhone developers have downloaded the beta firmware and found out the new features come with this update:

Here are the known features and possibly more to come soon:

For iPhone User:

  1. (For iPhone 3GS only) Now Video Editing gives you the option to trim your clip then “Save as copy…” rather then replacing the original video clip.
  2. (For iPhone 3GS only) Voice Control works over Bluetooth.
  3. iPhone now vibrates when arranging icons.
  4. Updated AT&T profile to 4.2
  5. The baseband version is updated to 5.08.01. This will fix the holes used by ultrasn0w and makes ultrasn0w fail to unlock iPhone 3G. So, don’t upgrade to iPhone 3.1 beta if you need to unlock iPhone 3G
