For all the hype that Google's Android mobile development platform has received, pundits have also been critical that Android developers and vendors participating in the project have yet to produce an Android-based phone. Now, it seems, some vendors' phones will be later than others.

Reports were that Android phones would be out in the second half of this year, but Silicon Alley Insider says that only T-Mobile will make that happen. The T-Mobile offering is expected in the fourth quarter of 2008.

Citing a Wall Street Journal report, the story says Sprint and China Mobile won't debut their Android phones until 2009. And even though it won't do more than annoy Google, the timing isn't great for Sprint, according to writer Vasanth Sridharan.

Editor's Note: Thanks to Scott@AndroidGuys.com for pointing out that Sprint and China Mobile aren't delaying their devices. In an e-mail, Scott said:

We've been reporting an HTC phone from T-Mobile for better part of a year now and really no other devices beyond that...The WSJ is not reporting anything new beyond why certain companies won't have Android until later this year.
