Red Bull Mobile: Samsung Galaxy Nexus $665 with 365 Days of Unlimited Talk and Text + 5GB/Month
This was posted 11 months 8 days ago, and might be an out-dated deal
Though the price for the Galaxy Nexus keeps on going down ($400 currently), $665 seems like a reasonable price for 1 years worth of unlimited calls and text and 5GB data per month.

Essentially the phone will cost you $300 and the prepaid recharge of $365.
Unfortunately it uses the Vodafone network, which may not be great for some, though this phone should be able to use the 850 network.
There are cheaper overall alternatives such as purchasing outright and Liveconnected $11/pm Tribe plans, however for unlimited calls and text, it seems rather reasonable. Note that data is charged in 250kb increments unfortunately.
Edit: It's 250kB increments.
