Just so readers know, I'm based in Korea and the Nexus S model page in Korea says this as the antenna: HSDPA 7.2Mbps, HSUPA 5.76Mbps along with GSM support for roaming. When I picked up a Nexus S a few days ago, it came with version 2.3.4. However, I had to return it today because of some defective parts, and the replacement model I got was version 2.3.3. Am I missing anything from this downgrade, or should I request an upgrade? Much thanks in advance!
