Those stats (I'm assuming you're referring to AdMob press release) from from ads placed in apps, so they're likely biased.

If you search Twitter for "my droid" (which is admittedly not the most scientific way to find out), usually almost half of the posts are by women.

Just because the Droid doesn't have a feminine form factor doesn't mean females won't like it! Girls that care more about how a phone looks than its functionality would likely go for another phone, however, there are a bunch of us that LOVE the Droid. So much, in fact, that we've started a blog - womenwithdroids.com!

P.S. Several salespeople I've overheard at Verizon have no idea how to sell a Droid to a woman. Most women I know with one went in to the store looking to get it. I pay my bill in-store and have heard some salespeople totally losing sales because of their approach or things they failed to mention.
