Internet settings not applying!

[Guest deepower]

i switched to O2 a couple of hours ago and i have to set up my connections so that i can recieve my email. since o2 doesnt supports mms settings sending i had to enter all the information myself. I opened the normal settings (WM default) and ı opened connections and then tried to add a new modem connection but after like 7-8 tries it didn't saved my settings at all. When i enter the information to the fields and than tap the ok button in the upper right corner i'm again redirected to the modem connections page and still the list appears empty, which doesn't makes sense because i just entered them and clicked ok.

PLEASE! help because i have to recieve my work mails since they carry sensitive information.

thanks,
