My NA UMTS Pre 2 has weird issues with mic. It gives some distortion to my voice, so my friends can't understand me sometimes. It seems to be software trouble, 'cause sometimes it works ok. But mostly very bad (same thing with headset? voice recorder and so on). Doctored - same trouble! Is there any tricks to make something with mic sensivity? And will hp warranty this phone if i bought it unlocked through ebay?
P.S. I use it in Europe in GSM 1800 mode if it helps.
