Hi,
I'm just wondering whether DC-HSDPA will help at all on my iPhone 4S. If I'm understanding it correctly, then there are essentially two networks running in parallel (obviously with plenty of shared equipment) which I'll call "A" and "B".
Without a DC network, all devices must connect to "A" since that's all there is. Obviously with DC, a DC-compatible device will connect to both "A" and "B".
My question is whether an older device, such as an iPhone 4S, is able to connect to the as-yet-uncongested "B" and therefore get a speed boost? Obviously it can't connect to "A" and "B" at the same time, but is it able to choose the least-congested network to connect to, or will it always connect to "A"?
Hopefully I've explained that clearly enough :)
