i had problems with my n810 trying to download games.. applications.. etc.. because when i downloaded on my n810.. it tells me that other applications were required and stuff..

so.. i restored my n810 to have it clean and start from 0 (zero).
now my question is what do i have to download? things that i should download.. so my problem mentioned before does not happen again.

please help me~ and sorry for my bad english.
