ios 4.2.1 jailbreak

0

To jailbreak the latest ios 4.2.1 firmware on any device, go to the link below, download the software for your operating system and follow the on screen instructions.

As usual, if you want to stay jailbroken, do not update to 4.3 when it is released sometime in the next few days.

Also note that at present no unlock is available for this firmware at the time of writing.



Update: I have successfully jailbroken two devices using this method on windows7 and macOSX without any problems. The instructions are easy to follow.

APP HIGHLIGHT 1 : Navfree UK & ROI

1 comments
Welcome to my first post of a new series entitled "app highlight". In this series I will aim to highlight certain iPhone applications that the reader may not have discovered that I think are worthy of a mention. Considering the app store now has more than a quarter of a million apps available to download, sometimes it can be hard to find some great apps that are hidden away.

Navfree UK & ROI

As it's name may suggest, Navfree is a free satellite navigation app for the iPhone that offers a great alternative to other applications such as TomTom and Navigon. Obviously the big draw to Navfree is it's cost, totally free! Considering the high prices of similar apps, this app has got to be worth a look for many people looking to find an app of this type before spending their hard earned cash.

It is worth a note also that there is also a version of Navfree for the US, great if you go there on holiday asn it saves spending a large sum of money on a competing app that you may only use for a couple of weeks.

It is worth noting that although the app itself is free, if the user wishes to also have the app highlight locations of "safety" (read "speed") cameras and alert the driver to their presence, this must be bught as an in app purchase costing a not unreasonable £1.79 in the UK market.

The app includes all the other standard "sat-nav" features such as turn by turn directions, voice guidance, auto re-routeing and also includes live google search as a bonus.

It is excellent to note that the maps are downloaded to your device, meaning you do not need an active internet connection to follow your route on-screen (similar to a dedicated sat-nav) saving you money and battery power. One downside to this is that the app is 257mb which may be considered large if you have a lot of music, videos or other content already on your device.

I am taking a trip this weekend in which I will be utilising this app, so expect an updated review shortly. In the meantime try this app yourself by visiting the following link:


Check back for more "app highlights" soon!

UPDATE #1

Having used this app to navigate a 4 hour drive over the weekend, I can safely say that compared to rival apps such as tomtom and Navigon, Navfree offers outstanding value with little to no difference in quality compared to its competitors. GPS reception was always strong and there were very few issues with the maps in the software and the directions issued. I highly recommend that users try this app before purchasing alternative software.

It may also be noted that battery consumption whilst using this app isn't as severe as it could have been with an hour of navigation using approximately 15-20% of the capacity of the battery of an iPhone 4.

Can I jailbreak?

This depends on your device and your firmware. Not all devices on all firmwares can be jailbroken and you may have to wait for a jailbreak to become available.

If your device has firmware of 4.0.1 or below, it is very easy to jailbreak, and you don't even need a computer. Simply open safari on your device and go to the website "www.jailbreakme.com" and follow the onscreen instructions.

If your device is at firmware 4.1, it can also be jailbroken using Limera1n on mac osx or windows operating systems on your computer. Instructions can be found here

If your device is at firmware 4.2.1, the only jailbreak you can perform is tethered and you will need to connect your device to a computer whenever you wish to turn it on. I do not recommend jailbreaking your device in this instance and would instead advise you to wait for an alternative jailbreaking method.

If you have any interest in jailbreaking your device in the future, I would advise you not to update your iPhone firmware at any time until you know that the firmware you are updating to can be jailbroken. Remember also that if you update the firmware on a jailbroken phone your jailbreak will be lost.

The new and annoying iPhone SMS tones

0
If you are anything like me, you probably find it annoying when somebody in the near vicinity receives a text on their iPhone as everyone seems to use "tri-tone" as their message alert. I have always found this annoying as this causes everyone to reach for their phone as they are unsure whether it is their phone or not.

ios4.2 brings some good news.
The new firmware adds a number of new message tones, something I feel should have been added a long long time ago.

There is also some bad news however. They are terrible. For a sample, check the link below and watch the video and feel free to comment below.

App highlight: CineXplayer

0
If you had been following my blog over the summer, you may remember a post I wrote about how to convert video for your iPhone, iPod touch or Ipad. In this post I described how currently to get your .avi and .xvid video files onto your iDevice you needed to use a conversion program, but now, finally, this is no longer the case.

A new app, with specific iPhone/iTouch and iPad versions, called cineXplayer allows you to simply drag and drop your .avi or .xvid files onto your device in iTunes for conversion free playback on your device. The app includes a video tutorial on how to do this inside of the app and can be purchased for only £1.19 in the app store.

In my opinion, this is an essential purchase for anyone with a quantity of .avi or .xvid files as it saves a lot of time and effort that would have been wasted on converting the files, however the obvious problem with this app is that the apps will be copied onto your device uncompressed, taking up more space.


Look out for more app reviews coming soon.

August update

Hi, I know its been a while since I last updated the blog, been on holiday for a couple of weeks and ironically a lot of things have happened in this scene over that time.

Earlier today I updated quite a large portion of the blog, the summary can be seen below.


Also, for those of you that haven't seen this yet:


Secondly,I have also added a poll on the right hand side of the homepage, please vote as it will help me make my blog more relevant and helpful if I know what devices to target my posts to.

Thirdly, I know I have not uploaded any new app reviews for some time, at the moment I am not quite sure what direction I want to take with this section of the blog so it is kind of frozen until further notice. I am welcome to any suggestions though so either post them here or write to me on twitter @bb0Nk.

Anyway, I hope you find the new content useful! If you have any suggestions for me, please contact me via one of the methods mentioned above.
