some of my long term performance plans are 'hitting pay dirt', and Cydia is much faster than it was before; that said, it isn't done yet: there's one more thing that I think is going to make a huge difference that isn't even in there yet but should be for the final release.
This version of Cydia is included in the latest release of RedSn0w, and can also be downloaded as deb file from here. But if you're on an iPhone 4 or other already jailbroken device, you can still install it. There are 4 different ways to do that:
MobileTerminal is a terminal emulator application for the iPad and iPhone. The version of MobileTerminal that is available in Cydia doesn't work with iPhone iOS 4.x and iOS 5.x. However there are beta versions that do work, but aren't on Cydia because they are still in beta stages. This tutorial will show you step-by-step how to install MobileTerminal on iPhone with iOS 4.x and iOS 5.x (tutorial for iPad is here). If you have old version of MobileTerminal installed - uninstall it in Cydia (Search - MobileTerminal - Remove).

It seams that hackers have had their hands on the iOS 4.2 beta 3 for iPad. But, as we know, there is no officialjailbreak for it. Recently the well-known iOS hacker posted aт interesting picture in Tweeter. The shot depicts an iPad running MobileTerminal, a jailbreak application, which gives users full access to the terminal command line interface. But it looks strange, because it means that the hackers missed the beta 4, which should be released this past Tuesday, according to the Apple’s schedule. This could signal that Apple may skip beta 4 altogether and go straight to a GM build sometime next week.
A few hours ago iH8sn0w posted a tweet that he is able to run jailbreak on the new firmware 4.0 beta 1. DarkMalloc, another developer who worked on the project, has just released new video that shows firmware 4.0 jailbreak on iPhone 3G:
The interesting thing, besides the presence of Cydia and MobileTerminal, is the possibility to have multiple applications open at once. That means that multitasking on iPhone 3G can be enabled. Officially Apple doesn't want to activate this functionality on iPhone 3G, just iPhone 3GS and later devices.
This is quite simple. If you did a jailbreak on your iPhone you need to change the default password. Why? Because hackers can access your phone, read your mail, sms, download other data. The second reason is because there are already several viruses (worms) that use these default passwords.
Some users have already performed jailbeak for firmware 3.1 and faced problems with several Cydiaapplications. Some work with no problems, others send the iPhone to Safe Mode. Here is a list of compatible and non-compatible apps.
Jonathan Zdziarski has deviced a way to disable this writing to disk, so that screenshots cannot be recovered. On a jailbroken iPhone, you can disable these screenshots with the following commands in MobileTerminal or through SSH connection to iPhone:
Screenshots themselves actually get written to /var/mobile/Library/Caches/Snapshots. So these commands delete this folder and symlink it to /dev/null, so the screenshots don’t get written to disk.
The side effect to this is that when resuming an application, you’ll get the default screen in the zoom-in effect. Once the application resumes, however, you’ll have your application screen back. For example, your mail application will always zoom to the front as if you had an empty inbox, but will quickly correct itself once the application resumes.
“To return to the default behavior, just delete the symlink and the directory will get recreated. Mind you, this has no effect on the many other pieces of data stored on the iPhone, and therefore your iPhone will always be at risk for leaking private data, especially to seasoned forensic examiners. Use at your own risk.”
First of all I'd like to say we all want to use legal IPhones and operators. So everything written below is for testing purposes only . Hopefully this technology will be avaliable on all IPhones sold worldwide. You also might need to recover your IPhone, so make sure you backed up all your data. I personally did everything without any problems and needs to recover. Everything you do is your responsibility, etc...
So let's start, because it's worth it! It's just one evening and you will be able to create your personal Javaapplication, compile and run it on the IPhone, and amaze all your friends .
