Radio problems with 4.00.10 ROM

[maxlw]

Ever since i've updated my rom to the T-mobile 4.00.10 the radio part has been acting weird...

I encounter poor reception (not all the time) and when it gives a 'no service' message, i need te reset a few times to get signal again...

I have a Dutch XDA witch radio 4.21

Does anyone have the same problem?

Yes, I do.
Try to unsubscribe GPRS service with your provider. It makes my rsu 4.21 rock-solid.
I found that last RSU version was able to work with GPRS service from my provider is 3.??.
Unfortunately nobody success in downgrading RSU to this old version.
