I fly with Jetblue A320 several time, everytime we land and stop in the gate I always heard this loud sawing sound from the belly of the plane. What is that sound? Is that a sound of someone trying to open the cargo hold to get to the baggage?
I don't think i ever heard it from any Boeing plane.

I think that i's probably just one of the many hydraulics components that are used to open and close doors or the conveyor for luggage. I've heard it many times too and it's just different than other planes.

I'm not sure. I've been on 10 A320-family aircraft (5 of them last year), and I hear it too. Except, I usually hear it after the start-up of one engine, while taxiing (to the runway), after the shut-down of one engine, while taxiing (to the gate), and after shut-down of the other engine. It couldn't be the cargo hold doors if the plane's moving, so I'm guessing that it's probably some hydraulic mechanism(s), and it's got to have something to do with the gear (while it's down).
On a similar topic, while one engine is on and the other is off (sometimes, they're both off when you hear this; that happened during boarding once), I heard a high-pitched tone (not the squeaks that you were talking about, something else), and it doesn't stop until the other engine is turned on or off, depending on the other engine's status.
A320-family aircraft make some pretty interesting sounds!

it is probally when the cargos are moved from the compartment out to the tarmac. The weight of the Box maybe rubbed on the wall or the floor. Another thing is it could also be the turning off of engines. The turbines can make that sound when the turbines are slowing down. It can be either or. Personally, I have only been on a 737 and a 747-400 and a 757

The A319 does the same thing.
It the hydraulic pump running from the APU (Auxiliary Power Unit) opening the cargo door.
And no, Boeing's planes aren't that loud, neither is the noise when they're cycling the landing gear.

it's the hydraulic pump operating to open the cargo doors.
