I was wondering the same thing. Whenever I get my first LTE phone (I will have to buy it outright), I would love to take it home and activate it myself so the Verizon people don't get their hands all over it, but it's not worth an extra $150 to me to prevent that from happening. If I didn't mind spending the cashola, I'd be all for it then.
Here's a code I found listed in another thread:
Then select Phone Information.
By default, it has "CDMA + LTE/EvDo auto" selected, which means that it will look for a 4G signal, and if it can't find one will then look for 3G, and then 1x.
But if you don't live in a 4G area, then you can change this to "CDMA auto (PRL)" which will only keep it in a 3G mode.
EvDo only seems to lock out voice calls, so don't change to that.
There is also a "LTE Mode" that will keep it in 4G mode, and not change to 3G in your noticing the phone going between 4G and 3G alot.
There is also the standard ##PROGRAM menu as well.
*Example: My coworker, on a sweet Midwest Wireless/Alltel plan about like mine, went in to the VZW store to get a Droid1, like mine. They told him that a plan change would be required, so he walked out. A month later he got his discount at an authorized retailer without changing a thing.
Ok I got my Thunderbolt last Friday and I love it but I have some issues and wondering if I should return it. 1st I use the headphone jack to play the music on my car radio and the left speakers were not working. I had to jiggle the wire alot to get it to work. One bumb the left speakers go out. I also tried it regular headphones and it does the same. Should they take it back for this reason? 2nd is the battery life. I have to chage my phone like 3 times a day when I leave the mobile network on. I tried juice defender but it doesn't install correctlly. Thanks
Has anyone else been noticing their Thunderbolt changing between 4G and 3G - back and forth - quite a lot recently?
I've had it for almost a week now, and Sunday I started to notice this. It can be sitting on my desk and show 4G with 1-2 bars, then go down to no bars, change to 3G for about 15-30 seconds, then back to 4G. It seems to mostly do this in the evening and night, not to much during the day. I looked into the service menu, and it will show -91 dBm when there are 2 bars of 4G, but then will drop down to -103, -105, and then change over to 3G with -94/96. Back and forth it goes.
I'm not sure if this is a phone issue (hardware/software) or a local issue with the LTE tower.
Are people still experiencing issues with buzzy earpieces? Or was that just a fluke for a handful of people?
This sounds like a pretty good deal
"Just a heads up: Some existing Verizon customers have been receiving an email offering the new HTC Thunderbolt for a low $149.99 after a two-year contract and $100 instant rebate. If you are in the market for a Thunderbolt and near the end of your current Verizon contract, chances are you fall within the range eligible for the discount. You can’t find it online, but a sales number (800-437-6132) should get you what you are looking for."

You DON'T NEED *228 ON ANY 4G PHONE. All VZW 4G phones use a SIM card which stores even your CDMA credentials on the SIM card using a CSIM UICC application if you were wondering.
The PRL now auto updates with OTA IMS SIM provisioning like AT&T/T-Mobile.
The Thunderbolt uses 4GV (EVRC-B) which supposedly boosts voice quality and allows VZW to boost voice capacity on the tower using the same amount of spectrum.
Maybe that's why the bty. life sucks but with updates it will get better as they optimize the runtime code.
4GV is the same technology that allows simultaneous voice and data on CDMA and LTE.
Set it to CDMA auto (PRL) mode if you don't live in a LTE area.
My other droids are on EVRC. Switching to EVRC-B is supposed to make the call sound better? But it uses more battery? But gives verizon more capacity? hmm
