guys..is there a way for me to transfer old contacts from an old sim card to the iphone 4 which uses the microsim?ive been trying to do it for my brothers iphone 4 and cant figure out how. im afraid that if i backup his old contacts in my 3gs,it would combine with my own contacts.anyone?

thanks in advance!

guys why did the wifi on my 3gs suddenly fail..i can detect all wifi but have different problem with each one.

Case 1: try to connect to house modem, entered password and my phone says unable to connect to XXX

Case 2: tried to connect to another modem, the wifi icon has a tick on it meaning to say ive connected but im still browsing with 3G

is this a problem with my phone or it just happened that bothe the modems have problems?
