[JP3]

I have a TP2 and have few complaints but I know have a problem maybe someone else has experienced. Phone worked fine shut it off when I went to bed last night upon waking up this morning I turned phone on, when putting in p/w it said incorrect p/w, so I repeated and same thing so as most I slowed down and made sure I put it in correctly which I did and same answer nfg. I have taken out the battery also done the reset button and useless exercises....How do I get into my phone ??? Anybody ever here of this.

Thanks for the help, I did not see anything in reference to this problem on boards..
