Um, I believe someone will have to decompile the SystemUI.apk and make an xml file that associated the HSPA singal to the H icon to the 4G icon. I don't have any expertise in it, but I can give it a shot when time permits. I think @tys0n might have a bit more experience in this area/
I came to that understanding from this thread: http://forum.xda-developers.com/gala...-hspa-t1633268
Note don't try to use that, it's not meant for our phone, I'll try it for BeanStalk,
Edit: My attempt at trying to replace the icons with 4g just resulted in the top bar just disappearing all together, perhaps someone with more experience can help you out. I'm sure there's a way to do it through the xml files but I can't find anything relevant.
An easy way would be to push the SystemUI.apk from "/system/priv-app/" to your computer.
Unzip it, go to "/res/drawable-hdpi/" and simply switch names of the H/4G icons, or LTE icons.
Open original SystemUI.apk again but without unzip, then just drag all renamed icons in there and overwrite the old ones.
This will at least change the icons in statusbar to show 4G or LTE instead of H.
Took me about five minutes, now it says LTE.
