I'm sitting here running all of the options for my upgrade. They cover the cost of a 64GB iPhone along with my service -
Unlimited data with 2 year contract - $120.61 x 24 + $299.99 = $3194.64
Unlimited data with NEXT - $120.61 x 24 + $799.99 = $3644.63
10GB Shared with 2 year contract - $109.50 x 24 + $299.99 = $2927.99
10GB Shared with NEXT - $109.50 x 24 + $749.99 = $3377.99
The total cost is less by switching over to the 10GB plan but... I don't think that saving $11.11 per month is worth giving up my Unlimited data plan. I'd give it much more thought if there was much more of a savings but it's only about 37 cents per day.
So.... I can wait until my current 2 year contract is up on October 18th then try walking into a store to buy a phone. It would be a month after the release so I might have a good chance or, I'd have to order one and wait a few weeks. I just talked to someone that should see his the beginning of November. Forgot to ask which version he's getting. Or, I can upgrade on NEXT Friday morning. That will cost me an extra $450.00 over 24 months. Comes out to 61 cents per day. And no, I'm not a car salesman
