Cell Phones scrambling Nissan Key fobs

I seems that if you own a Nissan Altima or the Infiniti G35, you need to keep the key away from your cell phone. Close proximity to the phone, when it is receiving a call, can scramble the electronic code used by the key fob. Once the key code is scrambled, you can no longer use it to unlock your car. Which basically makes it useless.
This could be a big problem. Especially for people like me who keep their phones in their pockets. Of course, I don't have the bad luck of owning a Nissan.
It does seem that this is something that could have been tested for in the lab before production. If the key fobs are that susceptible to other electronics, then there are probably other devices that can also affect them badly.
