Compare iPhone 4S with iPhone 4

Useful video comparing speed of iPhone 4S with the iPhone 4.

I remember when I had a work 3G and I went out and got a home 3GS the speed difference was certainly very noticeable.

I am at this time tempted to upgrade my home 3GS to the 4S, mainly because of the camera, but the speed it appealing too.

QR Code Vino

So are QR Codes going mainstream?

A few weeks back I mentioned how I had seen one for the first time on mainstream television. Now as I was opening a bottle of red wine (present from a friend) I noticed the QR Code on the back of the bottle.

I have found in the past that the iPhone is not the best phone for reading QR Codes and in the end I found that the best QR Code application was Optiscan.

Optiscan lets you create, scan and share QR codes straight from your device.

Having tried a few free apps, I found that if you have an iPhone 3GS then this app works the best. As the camera in the iPhone 4 is better, you can have more success with some of the free apps, however (as I have it already) I use Optiscan on my iPhone 4. I like how fast it is, how it can capture virtually all QR Codes I aim it at and the subsquent actions I can then take. For example it is very easy to e-mail my history of scans so I can use them on a desktop computer.

So though I have had very few issues with Optiscan with other QR Codes, I did find scanning the QR Code on the bottle quite a challenge. It took a fair few attempts to get it captured, but once I did it bought up a URL which then opened in the mobile browser.

Impressed it was a mobile version of the website and in French!

However one click and I was in the English version.

Now there wasn’t much on the site, no more than was on the bottle really.

However at least if I wanted to buy the wine myself I now had a record of it on my phone. Much easier with a QR Code than typing in an URL on the phone (which to be honest is the point of QR Codes really).

So that’s a TV programme on cooking, a bottle of red wine, wondering where my next encounter with a QR Code will be!

iPhone Portable Wifi Hotspot

One of the real benefits of running Froyo on my Google Nexus One has been the facility to use it as a portable wifi hotspot. I’m not sure how long I will be able to do this for now, as T-Mobile have recently changed their terms and conditions on using their network for internet. I do have a Web n Walk Plus extra on my (legacy) T-Mobile contract. Though if T-Mobile decide to withdraw that, I need to think about how I can connect to the internet whilst mobile. Instead of the Google Nexus One, I can always use my MiFi, with which I use a PAYG Three SIM card.

In the US, Apple have announced they are going to release a new version of the iPhone for the Verizon network. Now I am not going to use that, but in the detail, it has emerged that the Verizon iPhone will now be able to do a similar portable wifi hotspot trick that a Froyo Android device can do. Before this “tethering” with the iPhone was restricted to a single device and didn’t work with the iPad. An iPad would work with the iPhone acting as a portable wifi hotspot.

So at this time, I am thinking that if Apple (as is expected) release a new iPhone in the summer, and the UK telcos play along, I will be able to use the iPhone as a portable wifi hotspot. What would be nicer if they added it as an upgrade for the existing iPhone 4.


According to MacRumors and other sites it looks like that Apple are prepping a 4.3 upgrade that will allow existing GSM iPhones to have the portable wifi hotspot feature.
