Any problems using Wifi and Bluetooth at the same time?

[Sesquiterpene]

Hello everybody,

I seriously consider buying this phone, but there is one thing I must be sure about. My current device suffers from a conflict between the wifi and bluetooth, which means I can never use them properly together (e.g. stream music and listen to it on BT speakers). My girlfriend's iPhone 4 does it without a problem on the same system.

Did anybody already try to use wifi & BT at the same time? Does it work well or do they interfere each other?

Thanks!
