helloo everyone
i have a wine red Samsung d900 and use to have tmobile but changed my service to at&t yesterday. ever since then, i cant receive texts from some ppl in my contacts, while i get texts from almost everyone else just fine. i dont know if its something with the service or the phone thats causing this, but frankly, im out of ideas. anyone know whats up or what i should do?
andd to top it all off, my phone cant detect any bluetooth at alll. no other phone can find me either and i checked my settings and everything about 30 times and cant get that to work either.

so pleaseee, help a girl in need =) haha.
thanks.
