i probably don't have any info you don't (assuming you're following the story) but i do know that satellite dishes are very common in the middle east. it wouldn't surprise me if satellite phone and internet service are equally popular, particularly among the set of people who are most likely to be involved in twitter.
that said, i'm sure there are a lot of fakes out there right now, but there are those who do seem legitimate enough that the information from them is worth weighing against everything else as we try to understand this situation for ourselves.
[edit]
as with all news stories involving dubious sources, it's important that you establish a set of baseline facts of the situation that you can use to help evaluate the credibility of what you see. for example, if they mention eating breakfast, make sure it's not 6pm where they claim to be. if they mention locations, do what you can to verify them. fact check to the extent that you can. this won't keep you from being duped by a motivated person, but it can help you establish a comfort level with respect to how far you are willing to trust what you've learned. if something doesn't seem right, it probably isn't, but keep in mind that cultural and language barriers can dull your sense of deception.
