Man I remember that game it was quite enjoyable to wander around get new fish and all. I'd be glad to find something like that as well.
This. 2nd choice would be Legend of the River King loaded into a GameBoy emulator. Really. I can't think of a single good iOS fishing game. Seems that Sega Bass fishing could work well with touch/tilt/flick controls, but knowing SEGA you'd be paying cash to rent the boat and buy gas/lures...
