Query: Regret buying

I was quite excited to be getting this phone, given all its functionality. The size & key pad were not (and still are not) hinderancs. The ENORMOUS problem has been with its bluetooth functionality. I have spent over 25 hours talking with Nokia customer service & 2 different Bluetooth manufacturers (Belkin & Linksys). None can fix the problem. The bluetooth companies blame Nokia & Nokia blames the bluetooth companies. Meanwhile, my phone's functionality (a KEY reason why I bought this phone) still does not work, I've wasted over 25 hours with tech people, & no answer seems in sight. This has been an exhausting and extraordinarly disapointing purchase. I could NOT recommend this prodect - or Nokia, given their poor customer service - at all.
