Thanks very much for the reply...now since I am already paying for an unlimited data plan I hope they just swap the sim card for me as I have a corp account so I cannot increase the cost, but I assume the carrier wants to offload as many users to the LTE system to take pressure off the HSPA+ system and I am already on the highest cost unlimited plan....
