Unfortunately, efforts to segregate consumers into one social network or another are already well underway. The iPhone has Twitter integration, so you can tweet photos, links and locations to your followers. Android Ice Cream Sandwich asks users to sign up for Google+, setting the stage for more integration in the future. Windows Phones have Facebook and Twitter functions built-in, to the exclusion of Google+. Increasingly, when you buy an iPhone, Android phone or Windows phone, you're also pledging allegiance to Twitter, Google+ or Facebook.
A proper Facebook phone would kick this trend into overdrive, threatening choice with even more lock-in. Although social network integration is great for consumers, the segregation most certainly is not. Responding to All Things Digital, an unnamed Facebook spokesman said that "every mobile device is better if it is deeply social." I agree, just not on Facebook's terms.
