We all know that upgrading your Apple iPhone 3G to iOS 4 can be kind of a pain but the French mobile operator SFR is giving the strongest warning we’ve seen yet about the process.
According to a translated version of the page: “Updating of the iPhone 3G to iOS 4 software significantly slows navigation menus. Any update is irreversible (bold is ours, not SFR). This information concerns only iPhone 3G and not the iPhone 3GS.”
The move comes as Apple is facing some flack for its iOS 4 software. The firmware adds cool new features like multitasking, the iAd mobile advertising platform, a social gaming network and more to Apple smartphone hardware that can run the new mobile operating system – namely the iPhone 3G, 3GS and iPhone 4. Unfortunately, the iPhone 3G just doesn’t quite have the hardware specs to fully take advantage of this new platform and many users have reported issues.
This isn’t just a case of a few isolated Apple iPhone 3G users complaining about iOS 4, as a report suggests Apple is currently investigating the issue. If you’ve already upgraded your Apple iPhone 3G to iOS 4 and are regretting it, you can still downgrade to previous versions after jumping through a few hoops.

If Apple had its druthers, I’m sure it wouldn’t even offer iOS 4 to Apple iPhone 3G users because it knew the experience wouldn’t be as good as on the new iPhone 4 or the iPhone 3GS. It did warn that things like multitasking wouldn’t be available on earlier versions of its hardware but I doubt it pictured the kind of mess that would ensue.
We’re hearing reports that the new software makes the 3G super laggy and downright unusable in some cases. I’ve thrown iOS 4 on my iPod Touch and have experienced some problems syncing and launching apps, so it may not be exclusive to the phones.
