I've got a few things to say about Sprint phones in here. A few apply to STi Mobile as well I think.
1. So you know about PCS Vision (1xRTT, faster-than-dialup internet access from Sprint). Now you'll need to know about Power Vision, which uses Sprint's growing EV-DO network to give people super-high-speed (think a fast DSL connection; 400-700 kbps) net access, music access, TV access, etc., in the big-city areas where the network is deployed. Are there any phones for it? Yes; they're just not shown on Sprint's website yet, not from the phones page at least. One, the Samsung A940, has tons of neat features and is going to sell for $250 (I guess with a contract). It doesn't look like a Sprint Razr any more but still, it's pretty neat to see the juicy feature list on this phone.
2. OK people, let's make the nice new Nokia 3155i a dud so STi can get it. The color, B&W-external-screen flip is Nokia's first Sprint flip and looks like a neat treat, especially since it's free. That makes for two Nokia phones that Sprint has, as opposed to zero for Verizon now (is the 6015i still around for INPulse?)...go Sprint! It's pretty neat too to see what used to be on our insternal displays go to the external ones, namely the beautifully readable network name, signal bars and battery bars (generalizing with this and the T-Mobile Nokia 6101; I'll talk about it later), except there's no Menu Navi key label ;). Overall I think STi won't get this one; it will be too popular of a phone. I'd like to be proven wrong though, especially if they can keep the price (after a rebate of course).
3. This is a little less earth-shattering but (I guess to make room for the Nokia) Sprint's Sanyo 200 phone is now $20 (okay, $19.99 but I'll give you a penny) with a contract. Let's hope that STi lets us have it for a little cheaper (free with rebate anyone?) when they come out with it. Or do they want people passing it up for the $20-more-expensive LG 225 cameraphone?
