I'm currently using KB3. I get good network at home but poor at work. KD1 seemed to give me the opposite!

Is one of these radios generally better for the UK?

I would not recommend flashing radio's with Rom Manager.
Not flashing it properly might cause some serious problems.

I used an earlier posted KD1 on my 9020a and its identical to KB3 to me. HSDPA all the way and the speedtests are about the same.

Reception flat out sucks on the NS though compared to other phones.

As to your question,
It is actually using HSDPA when it is able as sometimes it just wont show the H icon :p This is one of the glitch.

You tested both radio on your I9020A or I9020T?

No no, I have the H icon.. using CM7. so it's not that glitch... I'm checking on the About->Status settings anyway.
Tested both. KB3 is working great. KD1 - no HSDPA

I've noticed this as well. I was using KD1 for like a month or so, and then I saw this thread and noticed that I was getting HSDPA a lot more..I would on occasion see it on KD1 but not too often, even when I had damn good signal. I am happy using KB3 and the speeds are pretty damn good.
