Hey, I dont know if this question has already been asked and i didnt see it addressed so hopefully that isnt the case... I am currently on a tmobile plan with my company. We use a blackberry unlimited data package. Im looking to unlock an iphone and just pop my tmobile sim in. My question is whether or not tmobile will somehow recognize that it is not an actual blackberry and i will incure some extreme data charges. id hate to get a bill from my company at the end of the month for some ridiculous amount. So basically...will an iphone work with a blackberry plan without extra charges? Any help is appreciated.
