Jailbreak iOS 5 Untethered On iPhone 3GS (Old Bootrom) WIth Sn0wbreeze 2.8
So if you are lucky enough to have one of those rare early iPhone 3GS’ with old bootrom, you can enjoy full untethered jailbreak on iOS 5 beta right now using Sn0wbreeze 2.8b2 on Windows.
Apart from adding support for full untethered jailbreak for iPhone 3GS (old bootrom), everything else remains the same. You can jailbreak all other devices (except iPad 2) right now on iOS 5, but they will be limited to tethered boot only, which means that you will have to connect your device to PC/Mac on every reboot.
For instructions on jailbreaking using Sn0wbreeze, you can follow our detailed guide posted here. Users with iPhone 3GS (old bootrom) wont need to follow “Booting Into Tethered Mode” steps as they have now got support for full untethered jailbreak on iOS 5.
Alternatively, for both Windows and Mac users, Redsn0w 0.9.8 is also available which can jailbreak (tethered) all devices except for the iPad 2 on iOS 5 beta. Instructions for jailbreaking using Redsn0w can be found here.
It is important to reiterate the fact that beta versions of iOS 5 are currently available to registered devs only. Apple plans to launch final version of iOS 5 to public in Fall.

iPad 2: Everything you need to know iPad 2: Everything you need to know iPhone 4 review Reviews: iPad 2, iPhone 4, iPod touch, Apple TV White iPhone 4
UPDATE: Never mind, this worked in iOS 4 if you had DropBox installed. Clearly I shouldn’t blog before coffee. Sorry folks!
Looks like iOS5 may finally bring file download support to iPhone, iPod touch, and iPad. Previously, if you came across a non-media file link in Mobile Safari and tried to do something with it, it would just sit there, staring back at you — mocking. Now, in iOS 5, Safari will serve up an intercept page that offers to let you send the file to any installed apps that can handle it… which right now seems mainly limited to online file stores like DropBox.
It doesn’t appear to actually be working yet either. At least, several people who tried it got an “unable to open this document error”. So Apple could just be toying with the idea, it could require iOS 5 API support in apps that won’t come until the fall, or it could be tied into iCloud features that also won’t show up until the fall.
iOS has long been able to handle web links for music, images, and videos, for email address and iTunes store downloads, etc. In iOS 4, Mail gained the limited ability to open certain document types in associated apps. Safari getting the same ability would be convenient to say the least, though if you sent an EXE or DMG file to DropBox (or iCloud?) for later use on your Windows or Mac PC, you’d need to make sure it was malware free before doing anything with it.
What kind of files would you like iOS 5 to offer download options for, and how would you use it?
Daily Tip: How to downgrade from iTunes 10.5 beta on a Windows PC
Having second thoughts about iTunes 10.5 beat and wondering how to downgrade back to 10.3 on Windows? If you decided to take the plunge and try out the beta of iOS 5, you must also have upgraded your iTunes software to 10.5 beta. We have already covered how to downgrade your iPhone from iOS 5 to iOS 4.3.3 but what if you want to downgrade iTunes too? Well below is a guide to help you do just that.
A word of warning; before you start. This worked for me and should work for you too however there is always an element of risk, especially if you have a lot of content stored in iTunes. If you still want to go ahead and try it, read on after the break!
- Download the latest full build of iTunes here
- While that’s downloading, take an optional step to ensure your media is safe. Locate your iTunes folder which should be in C:\My Documents\My Music or C:\Users(your username)\Music in Windows 7. Copy the folder to another location just in case.
- Open Control Panel, Programs and Features and uninstall the following entries:-
- Apple Application Support
- Apple Mobile Device Support
- Apple Software Update
- iTunes
- Once all of them have been uninstalled, install and run CC Cleaner which will remove any registry entries associated with uninstalled programs. You can download it from here.
- Now reboot your Windows PC
- Once you are logged back in, go back to the location of your iTunes folder (Not the backup you made earlier) and find the file named iTunes Library.itl and rename it to iTunes Library.itl.old
- Open the folder Previous iTunes Libraries and find the file with the latest date prior to upgrading to iTunes 10.5 beta. In my case it was iTunes Library 2011-06-10.itl
- Copy the file and paste it into the root of the iTunes folder. When it has finished copying, rename it to iTunes Library.itl
- Install the downloaded version of iTunes from step 1
- That’s it, you should be done!
iOS 5 Features: Nitro Javascript engine comes to UIWebView, WebClips
According to a poster Hacker News, the Nitro JavaScript engine brought to iOS 4.3′s Safari browser, is now available to embedded UIWebViews and home screen WebClips in iOS 5. Apple originally claimed the Nitro engine, ported from desktop Safari, would make iOS Safari 2x faster, but due to restrictions on code interpretation (Nitro uses JIT, or Just-in-Time compilation), it was only available in the Safari sandbox. This effectively made web pages embed in apps and saved to the home screen feel twice as slow. No longer, according to this thread:
Q: Did they fix the bug from 4.3 where home screen web apps don’t use Nitro?
A: This is probably breaking my NDA to say this, but yes, they did. Web.app now has the “dynamic-codesigning” entitlement, which enables Nitro.
In other words, embed webpages and home screen web apps just became first class citizens, and should have the speed to prove it.

iPad 2 Air Mirroring Demoed On Video
We talked about Real Racing 2 HD’s AirPlay-based wireless mirroring feature for iPad 2 on iOS 5 at great length a few days ago. Today, the folks over at Engadget got hold of the latest version of RR2HD and tested in on iPad 2 with iOS 5 Beta 1.
Firemint’s implementation of wireless mirroring using AirPlay reminds us of Nintendo’s Wii U console. The execution is certainly different, but the philosophy is essentially the same.
The wireless-mirroring feature works like this: once set up, RR2HD uses iPad 2’s screen to display real-time information (like the circuit track, your position, speed etc.) while an Apple TV-connected HDTV displays the game’s actual racing action which you can control using the iPad 2 as a steering wheel.
Zach Honig, in his preview:
We installed iOS 5 on an iPad 2 and Apple TV, and took the latest version of Real Racing 2 HD for a test-drive, which enables dual-screen gameplay over AirPlay without the need for Apple’s $39 AV adapter. Other games, like Angry Birds, simply mirror the iPad’s display (and aspect ratio) on your HDTV, but Real Racing streams 16:9 HD video…
There’s noticeable lag between the iPad and Apple TV when using AirPlay, which may be an issue for games where timing is important, such as Rock Band, but didn’t seem to set us back while playing Firemint’s racing game. Overall, AirPlay offered a seamless gaming experience without a single hiccup — surprising, considering iOS 5 just hit beta last week.
As we predicated earlier in this post, there is a noticeable lag between when the user steers the iPad and when that action shows up on screen. Lag isn’t much of an issue for wireless mirroring when you’re not playing games on the iPad 2, but with Real Racing 2 HD – a game in which you win or lose on the basis of how good your timing is – this will be an issue.
The lag goes away when you use a $39 Digital AV cable. So if you want to play RR2HD properly on your HDTV, we would suggest going for the wired solution instead of the laggy wireless one.
Wireless mirroring for RR2HD on iPad 2 will be available when iOS 5 releases this fall.
