The Apple iPhone 4S allows you to send and receive messages and carry out phone calls using a number of different formats. This is achieved via both the standard formats as well as those provided by apps downloaded from the AppStore. In this article I will look at some of the communication apps available, so you can take advantage of the benefits they bring.
The FaceTime app makes its first appearance on the iPhone 4S, working alongside the handset’s built in front facing camera. You can only use the app if the person you are speaking to has a device with FaceTime (iPhone 4S, iPad, iPad 2 etc) and a front facing camera. If they have, then you can carry out video calls over a Wi-Fi network, so you can not only hear them but also see them in real time. This app is especially useful if you are contacting someone oversees, as you can avoid the notoriously high call charges associated with calling foreign number on a telephone. Because it is free, this app comes highly recommended hack whatsapp.
This is an app which allows you to send and receive SMS and MMS messages for free. Most iPhone 4S tariffs have an allowance of free messages included, but if you go over this allowance, an app like WhatsApp can be very useful. Because the app uses a 3G or Wi-Fi connection, messages incur no charges (although data charges may apply when using 3G in certain situations. To be sure, use Wi-Fi whenever possible). This app costs £0.69 from the AppStore and I think this is very good value as you can use it to send an unlimited number of text messages and media messages. You can only send messages using this app if your intended recipient also has WhatsApp installed on their phone. WhatsApp is also available for other operating systems like Android, so can also be used on phones like the Samsung Galaxy S2, for example.
As you can see, there are more options for communication on the iPhone 4S than the standard phone and message features. If you use apps like those outlined above wisely, you can significantly reduce your monthly phone bill. These kinds of apps are great for those who have lower allowances on their tariff or who use a Pay As You Go plan. There are many more such apps on the AppStore which allow you to communicate for free using an iPhone 4S; be sure to check out my other articles for details on some of these.
You can not realistically ban encryption. Encryption is used to protect communication through electronic devices; it protects your bank information and online accounts. This is cryptography, it is used in hundreds of systems. We have politicians speaking about banning these technologies. How can this be? British Prime minister David Cameron has raised a red flag on encrypted messaging apps like WhatsApp, iMessage, and Snapchat. He has called for the banning of these apps; implying that they are being used by criminal organizations and terrorists to communicate.
“In our country, do we want to allow a means of communication between people which we cannot read?”, rhetorically said by the Prime Minister
With this sort of logic I am going to go as far as to say; we should leave our houses and cars unlocked; and valuables left unguarded in public spaces because surely it would be much simpler to catch thieves and put them in prison hack whatsapp.
Security is not just for what the social norm calls the “good guys”. It is a two way street. I would rather have peace of mind that my data is being protected so well; to the point that Government officials can not tap into it. Think about the various ways this could go wrong. Imagine corrupt politicians with access to data or just consider that lightening up on security measures, will make it easier for the average hacker to gain access.
Computer scientists have spoken out on the futility of weakening encryption; so only Government officials have access.This same weaknesses can be exploited by malicious hackers. This view is held by many computer experts actively in the field.
A few months back a ban was called on WhatsApp in the UK; it has recently been dropped because of mass criticism. But this can of worms has not been closed just yet. This has just pushed the issue to other parts of the world; where they can theoretically gain some traction and spread. India has a ban on certain types of encryption. WhatsApp uses end to end encryption; which is illegal in India. WhatsApp uses a 256bit encryption which is only known by the sender and the receiver. India only allows 40bit encryption if you want to have permission you need to apply through the Government. The Indian Government has asked for the keys to be able to gain access; but WhatsApp creators have said they do not have them. So all user using the latest version of WhatsApp in India are technically breaking the law. No actions have been decided on what to do with the company; they are not based in India making things complicated. Recently Brazilian authorities have been reported to have been reported to be collecting WhatsApp data with the hopes of fighting drug tracking. WhatsApp has been cooperating with law enforcement; but have gone on to say that they cannot provide the full extent of what they want. We are just uncovering what’s on the surface; do some research on what your local Government and even internet service providers are doing; and what data they are doing with this data.
