Is this what your trying to do?
The problem with that is there is usually no level 2 traffic transmitted over a wireless link. Only end points (The cell phone, the laptop) can be connected to a wireless link. The first wireless connection would have to somehow have level 2 networking if the end points connected to the second wireless link were to work.
This can be done if you setup a Wireless mesh using 802.11s.
Or if you use some sort of a layer 2 tunnel, like L2TP through the first wireless link.
Or check out this post. They are referencing using ARPNAT and relayd. I don't know about those things yet:
There may be other options, or maybe I completely misunderstood your question.
