I know only small subset of people have had this trouble, but I'm one of them and I'm finally due for my upgrade. I'm tempted to wait for the Bionic, but I like the keyboard and don't need 4G, so the price on the D3 is more appealing.
HOWEVER, I am so frustrated with the cheek-dialing, cheek-muting, etc. I'm wondering if anyone who had this issue with D1 has tried D3 and found it to be better. The alternative would be to hope that the Bionic (since different manufacturer) might not have the issue. I need to upgrade ASAP because my phone is about done.
