first of all, if one phones gets it on a carrier , they ALL DO! its the same update.
So we all just imagined the problems with the Focus update where one variant didn't get it for months - somehow it was still same update that they got? We all are just hallucinating the updates that went to unbranded L800 phones but not to branded AT&T phones?
aside carriers don' t decide if ALL WP will get Apollo, MS does 100%
There is real-world evidence that you are wrong on this point, that while Microsoft has the first say as to whether a phone gets a particular update, carriers have the final say.
im just saying if MS decides to push Apollo to the NOKIA 900 and AT&T doesn't release the update .. NOKIA would be pissed and could possibly sue AT&T for not supporting a device they are SUPPOSE to support. because they where paid MILLIONS to support/ push it.
*not supporting a phone after a a agreement with a major RTM* = not holding up there part of the deal = not holding up a contract = could get sued.
You
would get p*ssed, but you are not Nokia. Nokia
might get p*ssed, or maybe not, it depends on a lot of things. Suppose they were both aware before getting into bed with each other that the Lumia 900 wouldn't be getting Apollo. Still think Nokia would be pissed? This is not a far-fetched scenario, it's what Thurrott and the "insider" leak from The Site Which Shall Not Be Named have been saying.
But let's follow your point.
If Microsoft releases Apollo for the 900, and
if the contract between AT&T and Nokia mandates the release of the Apollo update, and
if there is no way for AT&T to fail it for bogus reasons, and
if there is no way for AT&T to delay it indefinitely through testing, and
if AT&T refuses to release the update, Nokia could
possibly sue AT&T. Whether they are allowed to sue or must choose binding arbitration, which court they would be allowed to sue in, and what particular remedies they could pursue, are all going to be spelled out in their contract. If you don't know what the details of that contract are - and so far you've given zero evidence that you do - then you're just talking out of your *ss.
