I received a new v600 via warranty replacement from AT&T. My original phone was purchased around the June timeframe. I've noticed some differences I'd like bounce off the folks in this forum for feedback:
Old phone: 1) SW: 0B.09.2DR 2) Under network setup the speed is set to Continuous. 3) Black rubber circle left of speaker on back.
New phone: 1) S/W: 0B.09.2FR 2) Under network setup the speed is set to Medium. 3) Grey rubber circle left of speaker on back, inset somewhat.
You got an older phone with the warranty replacement. Check the manufacturerd date stamped to the right of the external speaker. Newer phones had the black antenna cover and around the antenna connection was a brass plate to impove reception.
