GPS resolution on phones is generally not high enough to pin-point your seat location. At least not on my iPhone 4.

Also, most of the theaters I've been block cell signals. Seems like a much simpler solution to me.

Theaters that offer assigned seating can automatically update your Tattlr profile with your seating for the given movie. In theaters that do not offer assigned seating, users would have to manually enter in their own row # and seat # after selecting their seats.

I've never heard of theaters blocking cell signals.

AFAIK it's illegal to block cell signals. Many theaters are cavernous concrete buildings though, which naturally reduces signal strength.

Rather than row/seat number just have a pictorial representation of the theater seating so they can tap on their general location.

Agreed. Thats even better.

That's true. GPS will only pin point you to 10m at a maximum.

But the theatre can provide limited WiFi to enable you to pin point your location even without being able to receive GPS.
