French carrier warns against upgrades to iOS 4

updated 10:30 am EDT, Fri July 30, 2010

Says iPhone 3G slows down 'significantly'

A French cellphone carrier, SFR, is now officially advising people against upgrading an iPhone 3G to iOS 4. The firmware "significantly slows" menu navigation on a 3G, the carrier says, adding that the upgrade is "irreversible." The upgrade should in fact be reversible, but only by more technically savvy iPhone owners.

The warning comes shortly after Apple itself finally admitted to upgrade problems. The 3G is considerably slower than both the 3GS and the iPhone 4, and may thus have extra trouble with iOS 4's enhancements. Other problems have been reported too however, such as heat and battery drain.

Apple is currently investigating the problem, but it has not said if or when a fix might arrive. One temporary solution involves rebooting a 3G, though if it works it may only restore speed for a few days. Some second-generation iPod touches are thought be affected by the problem as well, though to a lesser extent given a faster processor.

    Question

    If you buy an iPhone 3GS today does it come with iOS4? In those cases have people noticed a slowdown? (OK that's 2 questions)

    iPhone 3G, not 3GS

    @Geoduck

    It's the 3G, not 3GS, that is affected. My wife has a 3G and it does indeed perform sluggish with iOS 4--not horribly, but slow enough to notice.

    Well for my experience only for a few hours... And even with that small improvement the slowness is huge. :-(

    Technically neither of you actually answered his question. You just told him that this is about the 3G.

    To answer your question, Geoduck, it will come with iOS 4. And most people don't notice an issues with the 3GS (certainly not like the 3G users).

    And you can't downgrade (not that you asked that).

    Avoid iOS4 on older hardware

    My 2nd gen iPod Touch was unusably slow with iOS4, and the only new feature was the ability to put apps in folders! Not even wallpaper. My friends have reported the same issue with older iPhones.

    It took me a few days to work out how to downgrade it to iOS 3.x. iTunes checks with Apple to see if the iOS version is still permitted, and Apple's servers say "no" for anything other than iOS4, now. I almost resorted to jailbreaking it, but there are a few sites that explain how to work around this Microsoft-style policing (shame on you, Apple!). I had to do a clean reset to get the iPod to boot, which was annoying, but at least I can use my iPod again in iOS 3.

    In my opinion, this should have been obvious during Apple's testing. I'd have been happy if Apple said not to bother upgrading my old iPod Touch and still let me keep iOS 3. Perhaps they'll start to authorize the old version of the OS for older hardware, again. It would be easy to do, but perhaps they're more focused on saving face.

    Hated it

    I loaded iOS4 and regretted it immediately. I finally gave up on iOS 4 on my 3G and rolled it back for the same reasons. I got tired of waiting on everything. And after the install and restart of my phone the restore failed multiple times and I lost a bunch of pictures that I had not pulled off yet. .

    How to downgrade

    I did the upgrade- and ended up with a brick for 2.5 days- where Apple techs spent literally 16 hours with me- trying to get it back.
    I finally figured out how to hack it back- even though they claimed the upgrade was irreversible.

    I tell people if you have a 3G- don't upgrade yet.
    Apple screwed up- their boards were full of problems after the initial upgrade.
