Yeah those personalise and sounds settings are fixed in the next version. .
Regarding 4G Icon I can look in to it, the only problem I cant test is because here at my country we dont have 4G Yet.

You'll be happy to know that I can get Aroma to work with your ROM.
As far as carrier options go. It can have different version of the Phone app.
e.g. ATT's version will have the voice mail related and the other carriers won't.
I can also theme the current HTC apps you have kept to look more like AOSP ICS, and also hide the Sense version from being seen in settings.
How does all that sound?
