Most of you may not believe what I am about to post here, that is fine, believe what you want, I make zero money from this.
What has made these hacks possible has been security weaknesses in the code base, hackers are taking advantage of a security flaw to provide you a way to hack your phone. They are also advocating that you downgrade the phone to pre 1.1.1 version.
This leaves your iPhone vulnerable to attacks by malicious hackers and malicious web sites. This is how windows started in their for ever cycle of hacks and fixes.
The iPhone has bluetooth, wifi connectivity and can go to just about any site. If it has vulnerable code as has been shown, the same unpatched vulnerabilities can be used to load malicious software into your phone. The iPhone is a big target for malicious hackers and you are placing yourself at risk by not patching the vulnerabilites.
While it is true that as of yet, there have been not a single case of bricking due to the non-unlocking hacks, it does not mean that it will not happend. You spend 399 to 599 for the phone, do you care if it gets bricked? Maybe you have the money to get another one, but others may not be able to.
Telling people to walk around with an iphone that has published vulnerabilities due to lack of patching, is not responsible.
If you can, get your iPhone patched and keep patching it as they come out. Not patching is risking your iPhone, the data in it, and putting others as risk as your iPhone could be used as part of a BotNet network to cause problems to others in the Internet. It is not just your problem, others can be affected also,
Attack away, flame all you want. I will not be responding, as I have done what I could to make you listen. Now it is up to you.
PS I do not work for Apple, and I do not have any of their stock. However I been doing security for a long time now and I am providing you with conservative and responsible advice.
