Nexus S SMS issues

[Guest lambstone]

Hi all. I'm using a i9023 and rooted and flashed the latest Miui rom. By default radio was KB1 and I've been getting horrid data connection. Now that could either be due to my carrier or radio. Heard that KD1 was better and hence flashed it. Now sms sending is broken while everything else works still (I.e. receiving sms, calls, data, sending mms even). Could this be a result of flashing the radio?

EDIT: FIXED

I have a UK Nexus and have 2.3.4 incl KB1 radio and no probs whatsoever with data.

So I suspect it's your carrier, not the firmware. I'd downgrade to KB1 again...
