The other issue I have is in the 3G mode netflix doesn't seem to connect. Is anyone else experiencing this problem?
3G means base UTMS. H means HS*PA, 3,5G, standard that improves performance.
Android always switching to HS*PA, when some app requires internet connection and it's supported by network. When no apps seeking for connection Android reverts to base UMTS to improve network availability and to safe battery.
You need to check network settings. Or better contact your operator for that. Everything should work unless your operator have a problem with HS*PA.
But something tells me you are not honest with us. It didn't work for you in 3G. But you just installed Android 4 and forgot to mention that you didn't try yet mobile data on Android 4. You think that it was working in 3G because Android 3 based firmwares missed H icon, but in fact every time you connected by mobile network, device was switching into HS*PA mode without letting you know.
So there 3 points to you:
1. Check if APN is set correctly;
2. Check if you installed correct ROM that support bands of your operator (there is a lot of different versions - 301u, 301w, 302u, 303u etc);
3. Make sure HS*PA is not broken on operator side.
