...it work with T-Mobile Sim cards? I'm afraid that it won't work with T-Mobile. Also, does it work with T-mobile sim cards? Someone please help me!!!

This is very easy, if it's unlock you should have no problem at all. The phone should be either tri band or quad band, see, T-Mobile works on a 1900mhz. So this means that your T-Mobile sim card should work. Yes it will work if it's unlocked, enjoy it.
