Leave it to Billshrink.com to come out with a comparison of the total cost of ownership between the wildly popular Apple iPhone 3G and the recently introduced and sold out BlackBerry Storm.

BillShrink launched today a Blackberry Storm vs. iPhone 3G Comparison Site where consumers can view and calculate the real cost of each device and plan, features and related service head to head.

BillShrink helps consumers find the right phone and plan given their personalized usage patterns, e.g., how many texts you send, how many minutes you use, etc. In today’s tight economy, the site is helping consumers save an average of $340 annually on their cell phone bills.

Mind you, Billshrink has already saved me a few dollars a month already – almost $200 a year. Oh, and if you want other comparisons:

Storm vs. iPhone vs. G1
Storm vs. iPhone vs. G1 vs. Instinct

Nice. All of the data in one place to compare it.

Now… if Billshrink.com can find an instant way to avoid having to pay getting out of my contract too, it’ll get my vote for “best.thing.ever” instead of “just” being an incredibly good service that’s given me almost $200 bucks a year for beer my savings.
