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.
