Hey, everyone this is my first post, although I've been reading this forum since I got my Omnia HD.
Now if you're using the T-Mobile USA network like I am, most probably, you've encountered an issue with your voicemail indicator displaying. This issue bugged me to the point where I escalated it all the way up to the top with T-Mobile. Fortunately, I stumbled onto a thread where users reported success using the UAE JVIF2 firmware. The only problem is that I didn't want to use an old firmware especially when the recent ones add a lot of cool new features. So I decided to do an experiment and extracted the modem.bin file and flashed just that on top of the latest Hyper X firmware and it WORKED!!!
So regardless of what firmware you are running, just flash this modem.bin file and you should have your voicemail indicator working again.
