Actually, April 21 is the rumored date, which if that is true less than a month. And take my word, there wont be the date changes with a Motorola Android phone like there was with HTC. Moto had the first android, and theyve been firing them out like rockets ever since.
Unfortunately Lady, I had the same problems as you. I got a replacement and it is just as big of a piece of crapola as the first one I got. I think too many people look at the phone and say "This is awesome" and look past the serious issues the phone has. I am now awaiting VZW to send me a return box so I can ship it out. This phone, I dont care what half of you say, has serious antenna problems, serious battery problems and that is enough for me to say the phone itself is a lemon and is in no way living up to the hype. I guess they shouldve waited longer to release it.. My advice, to you is to return it before it is too late, and get your upgrade back and wait for the Bionic or the Stealth or heck even the LG Revolution. One thing is certain, the problems you are having, I had as well and I can say hands on that a replacement didnt fix the device.
But go inside a building and no one can contact me until I come back out and see sunshine. Anyone who loves their HTC TB and wants to part with their empty box for a small appreciative fee? PM me. I threw mine away like a dumbo because I didn't expect Verizon to go from full signal to no signal in one phone. I am back to my OG Droid. At least I can make calls and text again. Very sad. I liked the speed and the screen and the features. But after three factory resets with different techs and basically having to go stand outside at a certain spot to receive a call... I am done. Hope my Droid lasts. Reason I was getting a new phone to begin with. It is dying a slow death.
