Thanks...
Still can't figure out why I get only 3G-UMTS (instead of HSDPA) with the KD1 baseband.
KB3 works fine.

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?

Anyone from UK can give me some feedback?

I personally find kb3 slightly better in the uk, but not by much. Both radios offer good reception on Vodafone.

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