So you upgraded your iPhone 3G to firmware iOS 4 (or 4.0.1) and you want version 3.1.3 back? CNet specialists will show us how to do it:

There is a big a security hole in iPhone iOS. The device is insecure in a big and obvious way. You should be extremely careful of what sites you visit.

The FlateDecode vulnerability can be used when a PDF File is embedded within a Web page. Basically Safari tries to parse the PDF. And when it does it executes some code. Hackers can use this exploit to read and write iPhone data, get your contacts, sms, even delete something. So they can get all kinds to access your personal information stored on your iOS device.

Apple will fix it some day. Until then you need to take care of your iPhone security. There is a fix for that. It is available via Cydia for jailbroken devices. So you need to jailbreak in order to secure (funny isn't it?).

DevTeam finally released iPhone 4 unlock software. The new version 1.0-1 of ultrasn0w now works for:

• iPhone4 baseband 01.59
• iPhone 3G/3GS basebands 04.26.08, 05.11.07, 05.12.01 and 05.13.04

To install run Cydia and add the repo:  repo666.ultrasn0w.com

Recently Vupen, which is a French security firm, posted an advisory that contained information about two critical security vulnerabilities in Apple's iOS. After a while hacker comex used these flaws to create a jailbreak, which is now widely known and available on JailbreakMe.com.

But according to Reuters, yesterday Apple decided to react and its spokeswoman Natalie Harrison revealed that the company is currently investigating Vupen's advisory. So it looks like these exploits are going to be fixed soon!

Yesterday Apple released iOS 4.1 beta 3 for developers. Build number is 8B5097d for the firmware and 10M2308 for the SDK. Here is what's new in beta 3:

• A revised API that allows applications to have an access to contact thumbnail pics;
• Media playback enhancements, which include new classes in AV Foundation, related to batched playback, writing/reading and file compression;
• New features of Game Center: now players can track their in-game achievements and game scores on leaderboards and find teams for group play. But it was also found that Game Center is no longer supported for iPod touch 2G and iPhone 3G, though it is unknown whether it is a permanent change or not.

Final release of iOS 4.1 is expected to be shipped in September or October.

Many users reported that the first version of JailbreakMe broke the FaceTime and MMS features. The DevTeam fixed the bug.

New JailbreakMe users should simply proceed normally. The new version will not remove FaceTime or MMS from the iPhone.

Users who already installed JailbreakMe can get an easy fix. They should simply run Cydia and upgrade to the latest software.

Here is the quick 1 minute video of JailBreakMe working on an iPhone 4:

Here is the video of recently released universal safari jailbreak called JailBreakMe working on an iPhone 3G:

iPhone 3G and iPod Touch 2G work a bit slow with iOS 4. The video below shows a nice trick that will put the speed back in your device. You need to go do Settings and deselect Spotlight.

On iPod Touch 2G go to Settings - General - Home Button - Spotlight Search. On iPhone 3G go to Settings - General - Spotlight Search. Then uncheck all the searches that you don't use. This will increase the speed of your device.

This also works on iPhone 3GS and iPhone 4, however the speed increase is very small there.

MuscleNerd tweeted today that the recent redsn0w utility is able to jailbreak the iOS 4.1 beta2 on iPhone 3G and iPod Touch 2G. This is useful for developers only, however good news for everyone.

Here's some info from the DevTeam wiki page:

Apple released beta 2 of upcoming iOS 4.1. Developers can download ше and new SDK here.

MuscleNerd, hacker from DevTeam, commented via twitter on recent rumors that universal jailbreak (all iPhones and all firmwares, including iPhone 4 and iOS 4.0.1) will be released today. The basic answer is no, there will be no jailbreak today.

Not to make it a daily thing, but since somehow people thought it would be today: the new JB+unlock won't be out today

(there are issues with important apps like Facetime that need to be figured out...no sense releasing a half-broken JB)

There is no official jailbreak utility for iOS 4.0.1. However you can still jailbreak and unlock iPhone 3G. Just do the following:

• Download the latest RedSn0w 0.9.5-b5 in our utilities page here.
• Download firmware images for iOS 4.0 here.
• Run RedSn0w and point it at the 4.0 IPSW. (Yes – point it at the 4.0 IPSW even though you're at 4.0.1). This will also hacktivate your iPhone3G at 4.0.1 if you haven't already been activated by iTunes.
• Install ultrasn0w in Cydia (add repository http://repo666.ultrasn0w.com) if you need a carrier unlock (and in the USA, remember to turn off 3G mode in Settings→General→Network).

Here's what hackers tweeted about new Apple firmwares 4.0.1 for iPhones and 3.1.2 for iPad:

DevTeam:

As with *any* new FW, jailbreakers + unlockers must avoid this upcoming 4.1 update until our tools are updated

3GS, ipt3G, iPhone4 users (regardless of current FW or JB status) should backup 4..0 SHSH blobs http://is.gd/dskh9 soon

MuscleNerd:

Obviously avoid today's 4.0.1 update until JB tools are updated. Luckily, no baseband change so ultrasn0w lives on 🙂

each FW version has unique blobs. But using http://is.gd/dskh9 you can get 4.0 blobs on PC while you stay at 3.1.2

Hah for those iPhone3G or ipt2g(non-MC) users at 4.1beta1: use redsn0w from 2 wks ago to JB http://is.gd/dstU3 🙂

Following the release of the 4.0.1 firmware for iPhone and 3.2.1 for iPad Apple has released the SDK to go with it. Although the update seems like nothing, and is really is nothing, developers need to update in order to run their apps on new iOS 4.0.1 iPhone or 3.2.1 iPad.
