OK, so I have a T720 and it just flat out blows... A friend of mine has the 4400 and when I'm in analog he's still digital, my T720 locks up unexpectedly, sometimes it just doesn't ring and I get VM 2 minutes later, the alarm locks up the phone, so yeah it blows. My question. Has anyone taken their 720 to a Verizon dealer, complained a lot and gotten a replacement 4400 free of charge? That's what I'm going to attempt this weekend, but I was just curious if anyone had accomplished this feat already? Thanks!!!
