Ok so I hear that big red (Verizon) is going tiered on the 7th of this month right? I also read a lot about being "grandfathered" into your current "unlimited" plan... Now my serious question is do I NEED to have a 4G phone right now to have my "unlimited" 4G plan in the future OR can I stick with my DX2 till my upgrade on the 25th of this month?? PLEASE give me some insight on this because I'm really cracking my noodle over this and I don't want to spend 600$ on a TB or CHARGE if I don't need to. THANKS IN ADVANCE!!
