I added all the correct settings to my 770, including dial-up number, user and pass, etc.
When I pair the 770 to my KRZR k1m(Alltel) the bluetooth symbol keeps blinking. If I try accessing a site it becomes stable but then I get the error "Connection to phone failed. Try again?"

Can someone help me?

I get the same thing sometimes what i do is check to see if your phone has connections to the net, if not trun off both devices power on the phone first then your tablet if that don't work your phone may not be able to theater the tablet. Try google and see what phones are compatible with your tablet, i learned the hard way the best ones are nokia for nokia.. Good luck
