Even as old jobs, with the release of next-generation mobile phones, old iPhone4 was retiring, 5 disadvantages in the below, we'll look at it, looking forward to a new generation of iPhone5 will be improved.

Signal problem

When you truly held iPhone4 when its signal will be a hit, this is indeed a big problem for a mobile phone, although by the late signal rings, stickers and so on remedial measures, but is still not satisfactory.

Recommended models: Motorola XT883

As a veteran of the communications industry, Motorola's signal is good. Motorola XT883 in network is supported on 3 network mode, such as GSM,WCDMA,CDMA2003, supporting frequency bands include: 2G:GSM 850/900/1800/1900 3G:CDMA EVDO 800/1900 3G:WCDMA 850/1900/2100MHz.There is no pressure to go travel the world with the mobile phone.

Apple iPhone is coming, more and more iPhone fans are looking forward to it. What is more, they have purchased many cases, such as leather iphone cases, stylish iphone cases and bling iphone cases . I like the cool iphone cases.

Run memory processor is equipped with 1GHz and 512MB, keep pace with the latest Android 2.3 intelligent systems which run very smoothly. In addition, the machine also built a 5 million pixel camera, GPS, WIFI, Bluetooth are readily available.

Home button is to easy bad

Only a Home key on the iPhone4 that is responsible for an important task, exit the program, screen, toggle the background screen, and so on, thus began the long time Home key insensitive or even worse.

Battery life is not enough

Many people complained that the iPhone4 battery is not enough, playing games and see a film is to run up, it's not completely to blame Apple, which has become the modern Smartphone problems, powerful hardware is associated with low level of battery life, and focus on simple communication often long battery life of mobile phones.

The appearance modeling of Dell Mini5 is alternative, because the machine of measurements does very large, its screen size has reached 5 inches, equipped with has WVGA standard of 480x800 pixel resolution, picture quality also is good, fuselage back placed a star 5 million pixel camera, support continuous shooting and video shooting function, imaging quality is was satisfaction, system area is carrying Android intelligent system, common of wireless WIFI, and Bluetooth, and GPS, function is ranging.

Body materials is friable and not strong

IPhone4 used a glass material for the back cover, this design was very beautiful, but it brought another problem that was easily broken. In everyday use when accidentally dropped on the floor, rear door will break off. Though many iPhone fans have brought all kinds of best iphone cases, their beloved iPhone still suffer some accident.

To recapitulate, at present the only devices updated to iPhone OS 5.1, which you can apply Jailbreak (tethered) are equipped with a processor that Apple A4 or earlier-that is, iPhone 3G, iPhone 4, iPhone 1, 3G iPod Touch 4G and iPod Touch. For now there is no way to apply Jailbreak iPhone in 4S, iPad 2 and the new iPad, but as we said developers are already working on the solution and the prognosis is favorable. But, as always we recommend that it is best not to upgrade to iPhone OS 5.1 to have not been released to unlock tool Untethered mode.

The iPhone Dev Team has good news for users of the iPhone 2 and for those who will buy the new iPhone model. According comment on the method of applying the iPad 2 Jailbreak four months ago still running in IOS 5.1 so that the predictions of a Jailbreak for this model are positive. The process of speaking is not the ultimate solution but if that is the most important step to achieve the Untethered Jailbreak. Furthermore also ensure that this process could be applied in the new iPhone, so that users think are likely to buy the release will come soon. On the other hand, the hacker i0n1c yesterday issued a series of images of an iPad 2 with Jailbreak applied, which not only reinforces the idea that this time will not be so complicated they get overcome the defenses of this model.
