I agree.
Its like having a Porche and only going 20MPH with it.
It will get old after a while and you'd be like WTF? I feel like Im riding a mopad
Well, the savings is pretty considerable, despite the fact I get a 15% discount with Sprint, AT&T, and Verizon (not sure if T-Mobile would give me the discount with their value plan)
If I were to switch to the T-Mobile Value Plan of Unlimited Talk, Text, and Web (2GB prior to throttle, but no data overage charges), it would give us our two lines that we need for $100 per month before taxes.
The current Sprint plan I'm on now gives us 1500 Shared Minutes with Free Nights and Weekends, and Free Mobile to Any Mobile, with Unlimited Messaging and Data. It's $130 per month before taxes. Unfortunately, Sprint changed their contract after we were customers, and now this same plan will be $150 per month after we upgrade, including a $35 activation fee per line to upgrade the phone. This is their "Premium Data Fee" of $10 per line per month for using data with a smartphone.
The AT&T plan I am looking at is the Nation FamilyTalk 700 with unlimited messaging and mobile to any mobile, free nights and weekends, and 2GB Data Packs for both lines. This is also $150 per month prior to any discounts I get, which includes free activation. So, it will be the same as Sprint, except for losing unlimited (slow) data and about half the minutes. The minutes aren't a big deal because we only use about 250 minutes that actually count against our number.
Both Sprint and AT&T would make me commit to an additional 2 year contract, which is fine, but the savings of $50 per month is looking very attractive.
That would be a savings of $600 per year, or $1200 over the course of a hypothetical 2-year contract.
Obviously my data speeds would be considerably slower with T-Mobile unless they continue this spectrum refarming. So, even if I bought an iPhone 4 (not a 4S) for retail price, or even a 4S at unlocked retail price... it would pay for itself over the course of the would-be 24 month contract.
I could always get a Samsung GS2 or something and actually use the higher data speeds and lock myself into a contract with T-Mobile and still save around $50 a month, but I certainly want an iPhone.
My case for actually using EDGE is that my data speed with Sprint is quite awful right now anyway, so I don't feel I'll know what I'm missing. It's not like I'm coming over from HSPA+ to EDGE.
....
The only case I'd have to remaining with Sprint would be to hold out for the iPhone 5 with hopefully LTE support which could bypass this slow data speed issue. But I can't justify spending the same as AT&T and having very slow data rates.
