Cisco 2811 adding cellular services for redundancy

I have a cisco 2811 with two 1DSU-T1 V2 wic cards.
I have a dual bonded T1 coming in.

We have had several outtages lately and we need to get redundant access, we have several servers serving both DNS and IP based services, we were thinking about going with cellular backup from the same company that provides the T1's (Sprint)

I have two questions really...

What equipment or card do I need to integrate cellular into the Cisco 811?

Can I make a cellular backup automatically take over for the main T1's in case of T1failure for both outgoing and incoming traffic and be routed properly (no interruption)?

wow that looks great, can I assume this will take care of my needs?
I do not understand how data gets where beyond smple networking so I am at a loss as to how they would accomplish rerouting out incoming traffic to the proper device (cellular) when the T1 goes down.

is that setup by Sprint?

I understand how OUTGOING traffic can be rerouted but not DNS and IP based incoming sevices.

The only issue I see is that the IP that will get assigned will more than likely be dynamic; I am not sure if you can get a static IP with a service like that. I have always used the Cell backup as a backup for outgoing traffic and never had to worry about services that needed to be accessed externally.

You might be better with a peplink device and just getting a Cable/DSL connection and using that as a backup.

I believe the peplink has a built-in authoritative DNS which takes care of the job of distributing incoming user requests. I don't see there is any issue with this approach.
