contacts? not sure but I hold 400 plus
Only ownned this one for 4 days sofar cant see how to put contacts on sd however no reason with so much memory
and have ooodles of ram= 73mb left with nothing running.
I have one that may have damage ref the keys. Again, sheer luck mine was a used purchase and if I had been the original owner would have kept a screenprotector on it.. oh well..
Make sure you always carry a back up on sd, and back up on pcsuite, with different file names ... just in case.
Sorry you are way ahead of me with excel... cant answer that, just installed the latest quickoffice 5, seems ok.
Good luck
