Samsung Nexus S
You guys are dumb
...the camera is the same as the one in the other galaxy S phones so it will record 720p...
That would make sense, but for some reason it doesn't seem to be the case. Samsung and Google specs say it will only record 480p.
The network speeds supported by a phone are determined by its radio chip (hardware) and generally cannot be upgraded.
There have been rare cases where a phone shipped with hardware designed for a faster speed but it was limited in software for some reason (perhaps because software for the faster standard was not finished yet) and a subsequent software upgrade "unlocked" the faster speed capability.
But that is rare. In general, a phone that ships without HSPA+ will never be able to support HSPA+.
Since the Nexus S, is similar to the T-Mobile Vibrant, would there be a chance that the Nexus S has Quad-band 3G support, like the T-Mobile Vibrant has via a software unlock?
The T-Mobile vibrant is a Quad-band 3G device, but the 850/1900 3G bands are software locked.
Also, is what you mentioned about phones not allowing their full 3G speeds related to the G2? Many places T-Mobile has claimed to have super fast HSPA+ speeds, but when we do speed tests with the Nexus One, G2, Vibrant, etc. I am not seeing speeds near 7.2 for the HSPA devices. I even did a speed test in NYC on the G2, and it would not go past 2Mbps. It's rare that I find a tower that gives me past 2Mbps on my Nexus One.
