Starting this morning, Monday 3/21/2011, my Thunderbolt has been having problems keeping a 4G LTE connection even though I am in a very good coverage zone.
The symptom is basically, during network activity the phone will suddenly drop 4G LTE and lose all data connection. Then somewhere between 5-10 seconds later, it will re-appear. It will continue to do this repeatedly while I am attempting to use the 4G LTE network.
I've had to use the solution posted here, which explains how to disable 4G LTE and use just Verizon's 3G network:
While this solution works fine now, I would like to see if anyone else is having this problem and if it is a known issue.

its been about 14 hours since activating my replacement and it continues to cut in and out. spoke with vzw and they are now saying it is a known issue, no ET on resolution but expect a OTA update sometime soon. hopefully soon because i have only 10 days left to return this before being stuck with it.

Unfortunately, that trick did not work. My phone still drops 4G LTE during network activity occasionally, and then reconnects about 5-10 seconds later. It didn't do this when I originally bought the phone. It only started this morning.

may just be the area that you're in.

After I bought the phone, the phone worked perfectly at home and at work and didn't drop at all.
Now suddenly starting this morning, It's dropping my entire network connection, not just lowering down to 3G. It's completely disappearing, then re-appearing about 5-10 seconds later.
It might be the area I'm in, but why would problems start this morning?

I am having the same problem ...Ive had my TB for 4 days now and it has been doing this since I initially activated it. Called VZW a couple of times and have only been offered a replacement but I am hesitant to jump to the conclusion that it is a device issue.
Its the first 4G phone so I guess some issues were expected? I understand the *228 does not work for SIM cards ...is there another way to update the roaming?

your sim card does it automatically. there should be no need to update it yourself.

Using the Phone Info App does keep my 3G locked ...but where I am 4G is suppose to be available anywhere in the city (which is primary reason I purchased the phone) Thanks for the info ...atleast this way I can always access data apps without issue, maybe once the inconsistency of the 4G is resolved I can switch it back but I am thinking of throwing this one in a drawer and reactivating my DInc.
Havent tried it yet, but would another work around be just leaving the SIM card out?

Leaving the SIM card out will cause the phone to complain about a lack of SIM card.
