Um espião no iPhone
Se vocêestá pensando em desbloquear seu iPhone, cuidado! Um programa espião capaz de monitorar a navegação web, o serviço de GPS, a câmera e o microfone do iPhone foi demonstrado na conferência de segurança ToorCon, em San Diego, na Califórnia. Eric Monti, especialista da TrustWave Spider Labs, baseou seu código no programa Jailbreakme, usado para realizar o jailbreak no celular – recurso que torna possível a instalação de aplicativos fora da App Store, da Apple.
O código malicioso, batizado de “Fat”, tem o objetivo de mostrar como as mesmas vulnerabilidades usadas para realizar um jailbreak podem ser transformadas em códigos capazes de comprometer a segurança do celular.
A falha usada pelo “Fat” já foi corrigida. Ela foi identificada em agosto, já em uso para a realização do jailbreak. Na ocasião, o G1 antecipou que a brecha poderia ser usada por pragas digitais. O código criado por Monti prova essa possibilidade.
A criação de um código malicioso tem o intuito de alertar para os problemas de segurança existentes no iPhone, segundo afirmou o pesquisador. Ele alerta para a crescente variedade de aplicativos sensíveis, incluindo de acesso a contas bancárias, pontos de venda e outros, que tem sido colocado nos celulares com a percepção de que eles não estão vulneráveis a ataques.
O jailbreak foi considerado lícito nos Estados Unidos, o que tirou o estigma “duvidoso” da prática. A coluna Segurança para o PC do G1 já alertou para riscos de se desbloquear alguns aparelhos, entre eles o iPhone. O uso de brechas de segurança para a disseminação de códigos maliciosos, porém, pode atingir mesmo aqueles que tem um dispositivo bloqueado.

The Zune concentrates on being a Portable Media Player. Not a web browser. Not a game machine. Maybe in the future it’ll do even better in those areas, but for now it’s a fantastic way to organize and listen to your music and videos, and is without peer in that regard. The iPod’s strengths are its web browsing and apps. If those sound more compelling, perhaps it is your best choice.
Between me and my husband we’ve owned more MP3 players over the years than I can count, including Sansas, iRivers, iPods (classic & touch), the Ibiza Rhapsody, etc. But, the last few years I’ve settled down to one line of players. Why? Because I was happy to discover how well-designed and fun to use the underappreciated (and widely mocked) Zunes are.
Zune and iPod: Most people compare the Zune to the Touch, but after seeing how slim and surprisingly small and light it is, I consider it to be a rather unique hybrid that combines qualities of both the Touch and the Nano. It’s very colorful and lovely OLED screen is slightly smaller than the touch screen, but the player itself feels quite a bit smaller and lighter. It weighs about 2/3 as much, and is noticeably smaller in width and height, while being just a hair thicker.

This is getting a bit more subjective, but I much prefer the Zune Marketplace. The interface is colorful, has more flair, and some cool features like ‘Mixview’ that let you quickly see related albums, songs, or other users related to what you’re listening to. Clicking on one of those will center on that item, and another set of “neighbors” will come into view, allowing you to navigate around exploring by similar artists, songs, or users. Speaking of users, the Zune “Social” is also great fun, letting you find others with shared tastes and becoming friends with them. You then can listen to a playlist created based on an amalgamation of what all your friends are listening to, which is also enjoyable. Those concerned with privacy will be relieved to know you can prevent the public from seeing your personal listening habits if you so choose.
If you’re still on the fence: grab your favorite earphones, head down to a Best Buy and ask to plug them into a Zune then an iPod and see which one sounds better to you, and which interface makes you smile more. Then you’ll know which is right for you.
I’ll gear this review to 2 types of people: current Zune owners who are considering an upgrade, and people trying to decide between a Zune and an iPod. (There are other players worth considering out there, like the Sony Walkman X, but I hope this gives you enough info to make an informed decision of the Zune vs players other than the iPod line as well.)

The new Zune browser is surprisingly good, but not as good as the iPod’s. It works well, but isn’t as fast as Safari, and has a clunkier interface. If you occasionally plan on using the web browser that’s not an issue, but if you’re planning to browse the web alot from your PMP then the iPod’s larger screen and better browser may be important.

The very root of your writing whilst appearing reasonable initially, did not really work perfectly with me after some time.

The heart of your writing whilst sounding agreeable originally, did not really work very well with me after some time.

I was suggested this web site by my cousin. I am not sure whether this post is written by him as no one else know such detailed about my trouble. You’re incredible! Thanks!
Together with every little thing which seems to be building within this particular subject material, all your perspectives are generally fairly refreshing. On the other hand, I beg your pardon, because I can not subscribe to your entire idea, all be it refreshing none the less. It would seem to us that your remarks are actually not entirely justified and in actuality you are your self not even fully confident of the argument. In any case I did appreciate looking at it.
Really informative and first-rate composite stiff piece of articles, at the present that’s user genial (:.
The next time I read a blog, I hope that it doesnt disappoint me as much as this one. I mean, I know it was my choice to read, but I actually thought youd have something interesting to say. All I hear is a bunch of whining about something that you could fix if you werent too busy looking for attention.
Hi there friends, fastidious piece of writing and good urging commented
here, I am truly enjoying by these.

I do love the manner in which you have presented this specific problem and it does indeed present me personally some fodder for consideration. However, because of just what I have observed, I simply hope when the actual feed-back pile on that individuals remain on point and in no way get started upon a soap box of the news du jour. All the same, thank you for this exceptional piece and although I do not necessarily go along with it in totality, I regard the perspective.
Along with the whole thing that appears to be developing inside this area, your viewpoints are generally fairly refreshing. On the other hand, I appologize, but I can not give credence to your whole plan, all be it radical none the less. It seems to us that your commentary are actually not entirely rationalized and in reality you are generally your self not really totally certain of the point. In any case I did take pleasure in looking at it.
The very root of your writing while sounding reasonable at first, did not work very well with me personally after some time. Somewhere within the sentences you managed to make me a believer unfortunately just for a very short while. I however have got a problem with your leaps in assumptions and you would do well to fill in all those gaps. When you actually can accomplish that, I could certainly end up being impressed.
In this grand pattern of things you’ll get an A+ for hard work. Where you lost me was first in the specifics. You know, as the maxim goes, details make or break the argument.. And it could not be more correct at this point. Having said that, permit me reveal to you exactly what did deliver the results. The article (parts of it) is definitely rather persuasive which is probably the reason why I am making an effort in order to opine. I do not make it a regular habit of doing that. Next, while I can certainly notice a jumps in logic you come up with, I am not really certain of how you appear to connect the points which in turn produce the actual final result. For the moment I will subscribe to your issue but hope in the near future you connect your facts better.
Together with almost everything that seems to be building throughout this area, many of your points of view happen to be very stimulating. Nonetheless, I appologize, because I can not subscribe to your whole theory, all be it radical none the less. It looks to everybody that your opinions are not totally validated and in simple fact you are yourself not even completely confident of the argument. In any case I did enjoy reading through it.
