Upon some digging and trial and error I developed the following method which worked on two 2.2.1 Glaciers I had in possession. I think this is the simplest way to accomplish permanent root and S=OFF. This guide will assume you’ve got ADB set up and have some computer knowledge and are running Windows. Obviously I am not responsible nor liable for anything you do.

How to root HTC Glacier / Mytouch 4g (2.2.1):

1. Download Visionary APK and install it on your phone. -Visionary Home -Visionary Download
2. Download GFREE and extract it to your ADB folder
3. Download Terminal Emulator from Android Market
4. Download Rom Manager
5. Run Visionary, check Temproot on Boot and Set System r/w After Root
6. While still in Visionary click Attempt Temproot Now
7. Run CMD to your adb directory - CD C:/youradbdir/adb 
8. While still in CMD type adb push gfree /data/local and press enter
9. Unplug your device
10. Open Terminal Emulator and type su
11. Type cd /data/local and press enter
12. Type chmod 777 gfree and press enter
13. Type ./gfree  and press enter
14. Turn off device
15. After device is off: hold volume down and power, this will HBOOT. It should say S=OFF
16. Reboot the device and launch Visionary again, Attempt Permroot
17. Reboot device
18. Run Rom Manager and install Clockworkmod
19. Install your favorite ROM :)

PREFACE:

You can use a combination of Google Voice number and voicemail, your carrier number and voicemail, and Trapcall to have ultimate power and control over your phone.

• All calls which you hang up on are unmasked.
• All Google Voice calls go to Google Voicemail unless you hang up.
• All carrier calls go to carrier voicemail.
• It is impossible to unmask calls to Google Voice with trapcall so Google Voice should be used as the line that won’t get blocked calls. For me this is the business line.

INITIAL STEPS:

1. Go to your dialer and dial ##004#, this will clear all conditional call forwards.
2. Set forwarding as busy to Trapcall. *67*12062992100#
3. Keep other stuff default

BONUS:

• Use application Root Call Blocker to reject all Private & Withheld Numbers – this will ensure your phone call does not ring and you the call unmasked as soon as possible.
• Use trapcall app if your phone is not rooted to auto reject unknown calls.
• Read this for a better understanding of call forwarding.

This has only been tested on an android device so far, if this works please comment :)

This singled it down to either a carrier or software issue, so I factory wiped and put on a different OS.That was a huge waste of time so I began to suspect T-Mobile and called in to get support, they forced me to do 1 hour of tests and blamed me in the end because my phone is rooted. I went to the T-Mobile store and attempted to get a new phone number, they tried to force me to pay $15.

I called customer support and they would not give me the number until they did tests, I explained that I don’t have time to waste troubleshooting problems without getting paid and that I am a customer, not their tech support. The customer service finally relented and gave me a new number for free after saying that they are “99% sure it will not fix the problem”. It fixed the problem 100%.

So how do you fix this problem?

Get a new number from your carrier – it is probably their fault and they will use every excuse to say it is not. If this solved your issue post in the comments so there would be some sort of evidence customers can use to get the service they pay for.

By using Sony Ericson AGPS servers Google gets the boot and SE cannot link your GPS location to your person as they know nothing of you. Secondly I reference us.pool.ntp.org and north-america.pool.ntp.org while CM7, by default, only references north-america.pool.ntp.org

The full changes are as follows:

• Unthrottled service per this guide
• Agps kicked off to Sony Ericson instead of Google
• GPS Optimized for US territories rather than North America
• Wifi scan interval changed to 100 seconds instead of 15
• Removed protips.apk and email.apk – use K9 mail instead.

Download with Filesonic

Be cautions when downloading any third party packages, including mine.

Sometimes

One such instance is T-Mobile’s visual voicemail and I will show you how to fix the problem:

1. The first step you want to do is call T-Mobile customer (Tel:800-866-2453) and ask to have visual voicemail activated on your account.
2. Next it is important to have patience as you must wait – I was advised it would be for two hours.
3. If, within a reasonable ammount of time you are still unable to download the app from market follow do the next steps:
4. Get App Installer from Market
5. Download tmo-vvm-1-2-19.apk (mirror removed for copyright violation) and place it on your phone’s sdcard. You can get the newest version but as I can tell the only thing difference is an embedded advertisement.
6. Use App Installer to install the downloaded apk (It will not work with default installer)
7. Fin.

As a bonus – Google Voice offers a slightly better voicemail service. I recommend that you keep your private life out of Google’s servers ;). Out of all carriers T-Mobile has the best data retention policies, comparatively of course.
