Getting the Z10

Hi guys,

First time bb user here. I placed my order few hours ago.
Can anyone tell me what not to do when i get my z10?
For instance, when i got my nokia n9, i immediately accepted the latest ota update which meant i was stuck with that version. If i would have done some research beforehand i would have known not to.

So, is there anything i need to know about the z10? (i ordered a unlocked STL100-2)
