Kernel: DooMKernel v6
I used "StatusBar Z1 for GB" and didn't have any problems on my ROM/Kernel combination.
Maybe use the Status Bar download I noted and see if the problem still exists.
If not, then maybe a Status Bar build on the specific one you downloaded is an issue in which case the OP has a better idea of the problem.
I'm on a Vodafone 3G/4G network.
GSM symbol was correctly displayed even when dynamically switching back and forward between GSM and WCDMA
GSM is mind numbingly slow. .... how can you guys use it.... and yes I do remember dial-up AND.. acoustic couplers for 2,400 baud modems.
The 'active' data up/down indicators in the status bar is a nice touch.
