I have a question and i am real new at all this, what does that mean a DUN , and the picture there, was is it for? My husband and i have nextels , his is a i355 and mine is just a cheapy , i265.. some times on his in the recent contacts there is a arrow and a number 8 or some single number ,, what does that mean? the reason why i have a nextel is to get ahold of him or the other way around, if he can make or recieve calls , i wouldnt have this,.. does it mean that he is recieveing calls?

DUN means dial up network, it is used to connect you computer to the internet,
via a cell phone on a unlimited data plan through a bluetooth adapter.
The symbols on the recent calls list can be found in the users guide for your phones.
Do a google search for them.

DUN has nothing to do with making calls, and will drop you from the internet if you recieve an incomming call.
To make and receive calls, call each other and see what happens.

ok, thanks for the reply.
