Hi, i just got my blackberry 8700c and unlocked it to work on tmobile. I just started using it today and i noticed i dont have the option to make an MMS message. the phone is capable of mms and i read somewhere that becuase its a cingular phone thats why i cannot see that option. Is there a way that i can change my os to a tmobile version?

try os 4.5 but do you have a blackberry internet package on your line if you do not it may not work cuz you need data usually to send mms on at&t if you do not have a web package on a blackberry it blocks web access

Since it is unlock you might need to get some setting from your provider.

the 8700c does not have the functionality to send or receive MMS.

its service provider/service book limited feature

cingular/at&t doesn't allow other gsm carriers like t-mobile do
