1. Ah, yes it is. No Sprint isn't 'just as good'. It is way slower 'period.
It is available everywhere 3G is available. HSPA+ rolled about six months ago. I travel several times a week and ATT 3G with HSPA+ averages over 4Mps and peaks at 21Mps on my 3G network card. On my iphone I am constantly getting over 4Mps and that is the limitation of the iphone. All HSPA+ is or was is a software update to ATT towers with added backhaul, no new towers needed mostly software upgrade. Sorry, you're wrong there bud. Don't even talk about uploads, it gets more embarrassing.
2. No it isn't. You're not getting over 1Mps or 2Mps real world speeds, only 500kps to 1Mps. My wife has sprint, I know. She is ditching Sprint for ATT as we speak and getting a 4s.
I have the 30 unlimited plan, I use nearly 4Gb per month and have unlimited data and no throttling occurred yet.
I pay 230 per month for four lines, that is cheaper than you are paying now, granted I have a 18% discount, but even without it, That would be 270 or 67 per line, you are paying 60 per line. So for 7 a month, you are paying for a network that has average 3G speeds in the neighborhood of 700kps against a network with 3G speeds of 4 to 7Mps.
Don't believe the 'less burdened crap line'. Sprint 3G sucks. So does Verizon 3G sucks. ATT 3G literally destroys either. The iphone 4S will have the designation as a 4G device. In jan ATT will be upgraded to 21Mps, so you will see real world speeds of 14Mps. The limit of the iphone 4S.
So on sprint, you will be stuck with 700Mps average speeds with nothing getting faster anytime soon. Even worse sprint's LTE rollout is taking place 2013 at the earliest. No LTE iphone on the Sprint network until the iphone 6? Hopefully they can get some towers going next year just to use a LTE iphone 5, but that is a long time to wait. Can you say invested in the wrong tech? WIMAX, was a bad idea from the start.
good luck with browsing with those speeds. lol.
Yeah good deal.
