OK here is what I did. I have been using my Veer for over a year, profile Dr Skipped First used but tied to my account.
I installed Impostah and decided to switch it over to just my profile. It has been working on my TP for over a year and it said my login was my email address so I thought it would be ok.
Well I lost all my back up data and when I SMS it locks up after send and says "messages can no longer be sent or received in this conversation." If I type in the phone number again I can send it once but then the same message comes up.
To make matter worse, I gave my daughter a new Veer, unlocked and in Devmode, acvtivated. It was working fine but had no back up because it wasn't tied to a profile. I tried to authenticate it as well using Impostah and the same thing happened to her phone.
