phoneis

i have a nokia 6133 phone and i am trying to sell it in order to get a cingular 8125 phone i was wondering can i insert my tmobile sim into the cingular phone and would it still work?..ohh and btw i have myfaves on my tmobile sim card soo will that be affected??

I really like it but theres a couple things i'm unsure about such as how well is the touch screen, durability, and how is it in general? Oh and i'm pretty much a big on texting-how many messages can it hold?
