Would GPS work? Isn't the ISS in a higher orbit, so above the GPS satellites?
The GPS constellations orbits much higher than ISS, around 20,200km up.

I think you're partially correct, that it's just a PR stunt. But it could also be to test how rugged common commercial products are, since part of NASA's new direction will be utilizing commercial means. But, mostly, I do think it's an attention getter - "hey, look, cool phones in space!" This is likely the biggest space launch NASA has had in ages and will have for years. They wanted to take advantage of it. I'm surprised they couldn't get Coke to advertise all over the external tank.TBH I think that the inclusion of the Android (conveniently, erm, left out of the MR summary) and iPhone is a cheap attempt to get some media/popular interest in the NASA programme - I'm sure that all of these experiments could have been done better with an Atmel AVR, TI OMAP or Altera eval board and some sensors. But whatever. The application for these apps sounds rather contrived.
So, they aren't ever going to go to Space again or what? I bet they will build new shuttles instead of Atlantis in the future.
The definitely did because GPS is mainly designed to be used by the military, including ICBM's which fly very high indeed.At the altitude they are operating, GPS has an entirely different set of calibrations. Curious of the makers of the GPS chip-settook that into consideration when designing it.PHP:
GPS scrambling has been deactivated for years. There's nothing to stop the iPhone from getting a proper GPS signal, except for it not expecting to be miles up.

No, it's the end of the US manned space program. There is no replacement. Odds are you'll never see another manned launch by NASA ever again. It's all going to either be foreign countries or private. Most likely foreign countries.
According to Android Central, there are a few Nexus S phones on board too.

You may want to check your facts, the Orion MPCV is already being built and the prototype model already in early testing. This is a NASA vehicle and will be used for future manned space flight into deep space.
Actually, GPS works fine at those speeds.
The problem would more likely be 1990s US federal law, which prohibits civilian GPS units from displaying information above 1,000mph or 60,000 feet... except in special experimental circumstances (and I doubt Apple modified these units' code).
GPS theoretically works at those speeds, and does so in some mil grade GPS devices. However, since it is illegal for consumer devices to output any info saying they are actually working at those speeds or altitudes, the chips used in consumer GPS products are unlikely to be designed or tested to actually be able to keep up with the GPS calculations under those conditions.
To be fair to OP, he did cancel its replacement.
Yeah, there are a ton of 14k mountains around these parts and I've been up a few of them with an iphone. Needless to say it works just fine.
there is still a replacement, it's called the Orion MPCV; there's already prototype models and early testing has already begun and will continue. The difference is, it's a capsule and not a shuttle.

With Ares scrapped, do they have plans for a replacement rocket?
Probably not. The reusable-ship method turned out to be costlier than originally planned. It's likely that future missions will use more disposable parts. So...not "shuttles."
1. The Shuttle Proved That Reusable Launch Vehicles are Not Cost Effective
This is a pernicious myth‚ one that has driven NASA policy for years, since the failure of the X-33 program and through former NASA head Mike Griffin's policy of reverting to expendable systems with the now-canceled Constellation program. But the reality is that the shuttle taught us nothing about the cost of a properly designed, fully reusable launch system, because that's not what it was.
The external tank was thrown away on each flight, and the solid rocket boosters had to be rebuilt every mission. The only "reusable" part of the vehicle, the shuttle orbiter itself, required extensive inspection and maintenance between flights, with a vast army of technicians costing billions per year. These high costs and headaches were not the result of any intrinsic technical issues with reusable vehicles, but were caused by penny-pinching during development in the 1970s. Spending more then could have created a truly reusable vehicle later. But it is always easier to slash budgets now and let some future politician have to worry about operational costs down the road.
