hello there,

right im a touch screen phone newbie, got my iphone 4 8gb yesterday 2nd hand and give it a full charge, its about 4 month old, pretty minted condition for 250, which iv been told a bargain as my friend just payed 140 for a minted iphone 3gs haha.

as its my first touch screen jobbie, iv been using it a lot as ya can imagine all cool stuff etc, connected to wifi all the time and on messengers.

my battery though is 41% allready, it says since last charge usage 7 hr 15 mins, standby 18 hr 10 mins.
is that good ?

and also, iv downloaded most essential apps iv been told to get,

facebook, fb chat, whatsapp, windows live messenger, twitter, a handy app to turn the light on or off etc.

is there any other apps i need that are usefull?

thanks
