Crowd-sourcing this a bit because nobody at Verizon seems to know for sure or can give me a straight answer with any bit of confidence. Sorry if this is a bit redundant, but at least it's not another iPad mini/Retina display thread, right? and this is trying to drill down a bit more from other discussions. Anyway, anyone have this who can walk me through the pricing here? as I understand it we've got Prepaid: $20: 1gig $30: 2 gig $50: 5 gigs $80: 10 gigs. Share Everything: $40: 4 gigs ($30 for 4 gigs and $10 "Share Everything") other tiers of share everything. Questions around Share Everything: Q1: Can you upgrade your plan within the same month? Can I go from $20 1 gig, then when i'm about to hit the 1 gig, move to the $30 to gig, or do i have to pay an additional $20 to get an extra 1 gig? Q2: Can I move from a prepaid plan to a Share everything plan? Q2a: If yes, can I do that within the same month? Or do I go Share Everything one month, Prepaid the next? Question about process/logistics: Q1: I can go month to month, cancel it one month, order it the next. Can I do this directly from my device, or do I have to call? Q2: SIM CARD non-use issue: wassup w/that? Q3: I have a Sprint ipad Mini right now but i'm within my return window. Would I HAVE to bring this thing back and buy an entirely new iPad mini, or could I just cancel my Sprint service, hit a few buttons, turn a few screws and voila, have a Verizon device? THANKS!!! feel free to make this a catch-all for Verizon Q's as well.
