I got Sprint service with the Data share plan. I have a Blackberry 7130e that was given to me. My wife has a Palm Centro Smart Device and according to the paperwork it can do the same. The guy at the store said you couldn't use it as a modem unless you have a certain add on plan that is $40. I just tried it with mine and it works. Since in my plan its has unlimited data, do you think I will get charged extra? Cause if I wont then I will get rid of the net at the house and just use the phones. Are any of you doing something similar.
