"isnt this small enough to look like space debris, and maybe dangerous?"
The fact that they said this burns up when it runs out of "juice" implies that it is in very low Earth orbit, where the atmosphere still exists and imparts drag. These will reenter the atmosphere on a moderately predictable time scale and burn up. Space junk is only a problem at higher orbits which can be stable for very long periods of time without propellant.
As for 2... they put on up and it worked. What's the point of theorizing about how it might not work, when they've already done it? It might stand up to a good solar blast, but that's hardly a surprise, and if it's disposably cheap, who cares?

the phone itself might be cheap, but putting it up there is most certainly not (yet)...which is why most things that are designed to go into orbit are expensive :(
would you care to spend 150k+ to put a $300 cell phone into space for 2 weeks?
Cubesats are always secondary payloads, usually jettisoned after the first main stage burn. Their mass is insignificant compared to the main payload, so they usually ride for free.
So I can't speak for all conditions, but cubesats do not usually ride for free. The prices I've seen are usually in the 50k / unit range. So if you've got a 1U cubesat, expect to spend at least 50k on launch.
Part of the reason for this is that there are integration costs for attaching a cubesat deployer to an existing launch vehicle, as well as liability risks, control and thrust timing modifications etc.
heh, i was gonna add the clause *unless you're the NSA or have some deep pockets
i think as long as launches are limited, the asking price will be kept artificially high anyways to render the cost of the actual satellite minimal compared to the launch expenses, regardless if it's $300 or $300,000 going up.
