When i went to my friends house we were around the tv which doesn't have cable but it still receives the local channels, it came to my attention a noise coming and going from the tv i turned off my phone and it stopped, is there any known issue related to this, interference of some kind?.

Thank you.

any 2G phone are doing this interference when synching with network. receiving sms. receive calls , you can check this putting another phone near tv and send an sms to that phone
