Consumer Reports weighs in on iPhone 5 and whether you should buy one

NEW YORK - Consumer Reports is ready to put the new iPhone 5 through its battery of tests once the shipments start.

The organization expects the phone will perform well, as only the iPhone 4 had problems and that was a unique issue with its antenna. The early drawback deals with the adapters for the phone.

"The new connector on the bottom, which is a lot smaller. It won't fit. The new iPhone won't be able to dock with the accessories that are out there now. If you've invested a lot in speaker systems and other docks out there you are going to need an adaptor and Apple is going to charge $30 for one of those," Consumer Reports Senior Electronics Editor Mike Gikas said.

The adapter won't be available until October, and video and iPod out will not be supported.

So why did they do it? Gikas said it was necessary to keep the phone thin. As the screens get bigger, keeping the phone thin and light is a challenge.

The upsides to the iPhone 5 are that its screen is bigger, and it's 4G. So, users will see faster download speeds. The phone also is an LTE phone, so you'll see even faster download speeds if there is a 4G LTE network in your area.

Consumer Reports said there isn't as big a need to run out and buy one.

"The only reason to buy this new phone is if you really want an iPhone and you were put off by that smaller screen. And now the new model has a larger screen and faster data connection that all those Android users have been enjoying for the last two years. That's really the only reason," Gikas said.

Gikas also said don't switch if you are grandfathered in to an unlimited data plan. With the new tiered plans, you'll likely pay $10 more a month, if not more. It all depends on how much data you use.
