I had a droid x2 and it didn't get 3.0 despite being priced similar to an iPhone and it was less than a year old when 3.0 was released. This is very common with android phones.
Other than nexus phones, all android phones are at the mercy of the carrier and manufacturer. None of them get updated on the day a new version of android comes out, most experience long delays, and many see no major version bump.
When iOS 7 comes out next week there is no doubt I will be able to install it on my iPhone.
