THIS IS ALL SPECULATION on my part and the research I have done... But... The way {please keep your posts courteous} has worked in the past I believe the following reports has made their decision on all of us Galaxy S1 Customers:

(If the link does not work by just clicking on it, right click the link and open in a new tab or window)
If you also have noticed that lately since Froyo was introduced to the Vibrant on 1/21, {please keep your posts courteous} has gone silent about any kind of updates when before that they were saying that they are in the testing mode and such. (A reminder, word has it the only reason why Vibrant got Froyo was due to a class action suit that was filed. I'm not saying that is the right way to go but hey, it worked)
I believe that this has all been a feeble attempt on {please keep your posts courteous} part to fool it's customers so that they could get their product out to over 10 million users, and now they are going to concentrate on the promotion of the Galaxy S2 which will probably have 2.2 or higher. (I don't think they would be stupid enough to put eclair on it). Also for {please keep your posts courteous} to be the first company to put out a phone with Gingerbread (Nexus S) I truly believe that they have the technology to upgrade our Fascinates, they just choose to look at us like red-headed stepchildren.
I will say this, it's really sad. The Galaxy S Line is one of the best lines of phones ever made but they ROYALLY screwed up by not taking care of it's customers and I'm a firm believer in Karma and it will come back to bite them in the tail as word will be out on the street that {please keep your posts courteous} does not update their phones.
Finally Folks, I truly believe that this is NOT, I repeat NOT a Verizon issue. I have seen so many posts about this being Verizon's fault. Nope, this fault lies squarely on{please keep your posts courteous}, and for those who still feel it's Verizon's fault because they told you at the store they were gonna upgrade it in a couple months, then you have been fooled by the almighty Salesman.
I have to say, at least the DL09 Maintenance fix gave me my GPS back so I'm happy for now but I will NEVER EVER purchase another {please keep your posts courteous}Phone. Because they have shown that they care more about money and so much less about it's customers.
So enjoy your Fascinate... with eclair... because you get what you get. (and so did I)
Thanks for your time
