Unlocked my 9360, can no longer access internet

I recently bought an unlock code online, unlocked my phone and since then I can no longer get Blackberry Internet Service.

I called Fido, who transferred me to Blackberry, and it seems the service books have disappeared. I've down a full swipe of the phone, hard reset about 40 times, I did get to work again, but it stopped after 4-5 days.

Fido says its the handset (I didn't quite say that the phone was unlocked out of fear they would no longer help me, I bought the phone from them, so more like an omission) and I have to buy a new phone because there is nothing can do.

Has anyone experienced this? The mobile network works and so do Wi-Fi, simply cannot connect to email and any applications that use data. I have a data plan. I also had the SIM card changed.

Sorry if it is too late to reply, but
all you have to do is call your Service
Provider and Have them Re-Send The
Service Books To You. They Can Walk You
Thru How To Do That.
