iOS 4.1 Beta 2 was released yesterday and according to MuscleNerd, you can already jailbreak it using RedSn0w 0.9.5b5-5. If you’re not a developer, you shouldn’t mess around iOS 4.1 Beta 2 but I’m sure some of you won’t resist the temptation.

If you’ve updated to 4.1 beta2 on iPhone 3G or iPod 2G (non-MC), you can use RedSn0w 0.9.5b5-5 to jailbreak. Just point RedSn0w at the official 4.0 IPSW, even though you are on 4.1 Beta 2.

This will not hacktivate your iPhone so make sure you are on an official carrier. If you rely on an unlock, do not do this. Do not get anywhere near iOS 4.1 Beta for that matter.

MuscleNerd notes that you may experience network problems after jailbreaking iOS 4.1 Beta 2. This will be a problem until the Dev Team updates RedSn0w.

Again, proceed at your own risks…

    I would be happy if they just came out with the darn thing and get it over with.

    This is just another reason for me to LOVE my wife for buying me the 3GS two months before the 4g came out. I will admit that I am one of the dummies to upgrade to 4.0.1 but only cause I was half asleep and when I read there was a JB for the 3g I thought I seen 3gs. So as I wait for the JB I at least see what apple has given us to play with.

    On another note, this new itunes no longer syncs only checked music in my general music list. Instead I have to go in and check artist, genres, etc. Each time it puts the whole damn music list back on my phone. Any idea if I am just seeing this wrong, or an easy work around to have it back the old way?

    Don’t you find it strange? 4.0.1 to 4.1? The jump doesn’t make sense to me.

  • le 4.0.1 avant le 4.0 ils on sauter une étapes lol

    This may be off the topic, but has anyone experienced worse sound quality from the loud speaker? It seems much worse on 4.0.1 than on former 3.1.3 It just doesn’t sound as loud and clear as it did before.

    Anyone else noticed it?

    If you look at iOS version history, you’ll see that x.1 updates have always come out in Sept when the new iPod touch is released/updated. Nothing unusual about the jump…

    I also have a feeling iPad will always be on x.2.

    Apple is a very predictable company if you pay attention to them. iPods always update in Sept after the “back to school – buy a mac, get a free iPod” promo ends. The whole reason for the promo is to clear stock before the new iPods arrive. If you follow their Mac updates, you’ll realize they usually update every 7-9 months (give or take a month). If you look at iMac updates history, you’ll see Early 2009, Late 2009, Mid 2010. So it would be safe to expect the next iMac refresh in Early 2011. MacBook Pro’s work the same way – Late 2008, Mid 2009, Early 2010… so expect a MBP refresh Late 2010.

    Early = Jan-Apr
    Mid = May-Aug
    Late = Sept – Dec

    iPhones will always update in June/July
    iPods will always update in Sept
    iPads will most likely update every Mar/Apr
    (think about it – that is a new iDevice every 3-6 months – perfect strategy for Apple)
    Most Macs will update (on average) every 7-9 months (although some have taken longer like the Mac mini and the Mac Pro)

    MacRumors has a excellent buyer’s guide that follows this trend and their guide will tell you when the last update was and if it is a good time to buy or not,

      Thanks a lot for a detailed insight. Definitely worth checking the recommended sources.

      When I was working at a soft dev co, tech support was issuing updates (taking apple for example) 4.0.1 -> 4.0.2…-> 4.0.9 -> 4.1
      What doesn’t make sense to me is the jump from 4.0.1 straight to 4.1

        Apple updates don’t work like that. A good example is OS X Tiger.
        Tiger didn’t stop at 10.4.9 and then jump to 10.5.x (which is Leopard). Tiger went from 10.4.9 to 10.4.10 and finally to 10.4.11 before 10.5 Leopard was released.

    i brought a iphone 3gs 3.1.3 from U.K in vodafone network and unlocked here in India. Unknowingly i did media reset and iphone was locked again and not working too. One of mi friend advised me to ungrade it to OS4 and unloking is the only solution. I did that too. Now mi phone has upgraded to OS4 but the problem is it is not unlocking? So hw can i solve this problem?
