So I'm currently running an old NexVision ROM (NexVision_2.3.1_02_VZW) with radio 3.27 which was the latest available at the time I upgraded.

Now I see the newest 3.42.50 radio has been released and I'd like to upgrade for better GPS reception. I'd like to keep my current ROM because I've gotten used to it and I like the features. Can I just flash via the SD card method and keep my current ROM or do I have to upgrade my ROM if I want to use this new radio?
