Here are the five most important Walsh made regarding the update, in chronological order:
I'm hearing the first #wp7 update is going to be MASSIVE!
@tomhounsell Haha, they've been working on this update long before they actually shipped v1 :
@keyboardP As @tomhounsell said, MS took 3 months to do what Apple did in 3 years. ;-)
@danvy Can't disclose the sources, but can disclose the details. More to come #wp7
@adamUCF Let's just say, they could have called it Windows Phone 8 :P
The first update to Windows Phone 7 will be arguably more important than any other. First of all, it will be the first attempt by Microsoft to update its new mobile OS and test its system to do so. Microsoft has tested its mobile OS update system before, but only internally, and never on a large scale. Secondly, it will show exactly how significant Windows Phone updates will be. Is Walsh right in that the update will be massive or will it mainly include bugfixes?
