I have a 8310 on the "blue" network missing MMS service books
Hello everyone,
To make a long story short, I have an unlocked BB curve and an old AT&T "blue" sim card. The phone works great, but I can not use MMS as the 'MMS transport' service book is missing (I have the MMS client service book). I noticed that when I pop in a regular cingular or new AT&T sim card, the missing service book I need appears.
I figure that I can buy an old Cingular sim card from eBay (as the new 64K AT&T and Cingular sim cards are incompatible w/ my plan), but will it work or will AT&T not switch my sim over to the Cingular sim card (although it is the older one)??
Does anyone know? Will they let me switch to the older Cingular sim card? I believe these are the one's Cingular first offered when the acquisition of AT&T first took place.
Your help is greatly appreciated.
Thank you.
