A US consumer watchdog has said it cannot recommend anyone buy the iPhone 4, according to a report in today's Los Angeles Times.
Consumer Reports, which is an independent, non profit reviewer of consumer electronic products, has published its review of the smartphone, and says it does not believe the device can be recommended because of an antenna design flaw that affects phone reception.
"The signal can significantly degrade enough to cause you to lose your connection altogether if you're in an area with a weak signal. Due to this problem, we can't recommend the iPhone 4," said Consumer Reports writer Mike Gikas in a blog post.
"Our findings call into question the recent claim by Apple that the iPhone 4's signal strength issues were largely an optical illusion caused by faulty software. It's a wonderful phone with a terrible flaw," Gikas added.
Apple has tried to claim the issue was actually the result of a bug that meant it under-reported signal strength, then said that holding the phone in a certain manner can affect the transmission and reception.
To avoid the problem, the company said owners should buy a £25 case.
It is the first time that Consumer Reports magazine has failed to recommend an iPhone since device was first launched in 2007.
