Swishing sound on iPhone 5 calls?

[Risco]

My iPhone 5 is making a swishing sound on calls. Anyone else had that issue? Three have been awesome and said I can go and swap it for a new one tmoz! I guess I am posting to see if it might be a network issue or phone?

It could be the phone, specifically the noise cancellation. In any case, swapping the phone out will answer that for certain.

Ahh that sounds like a plausible explanation. 😀 I will post back tomorrow and let you know how it is.
