Two of my BestMates, plus me, are using Motorola 3g handsets.

When connected to the older 2.5G network, they BUZZ like crazy at times...... other phones don't do it, only these Motorolas!!

It's so annoying, it's like when you put your phone up to a speaker or car stero... it makes that annoying humming sound! Except this occrs in the phone, it's almost as if the phone is interferring with itself!!

Anyone else experience anything liek this?
