Explanation of epst

[dagadus]

Can somebody please explain to me the epst setting in the MIP profiles? my data connection isn't working (i can make calls and sms), and i was told that my password is my 7 digit number. i've set up my data connection in the connections tab, but i still get the "#777 cannot connect for an unknown reason error" i am using a cooked kitchen based off of the no2chem 5060 rom (Awesome ROM BTW).

Thanks
