The ONLY thing you can do with another application open is listen to music. And no, in no way will this damage your iphone. It’ll just drain the battery a little bit faster.
the iphone inherts OSX’s mutlitasking environent, but apple simply locks it down, you don’t realize, but the mail app can check for mail in the background or the best example, the phone and SMS app will continue to recieve calls and texts. You’ll notice a little play icon when the music is playing in the top right hand corner.
@philo In the UK I can’t make a call and use mobile data (ie EDGE or 3G) at the same time. I can make a call and use a wifi connection. When a call connects the EDGE icon disappears off the screen all together.
@basp, the only main difference is the new 3G network, nothing else, apart from physical appearance.
and obviously the speed on the internets using the mobile internet
@Lightlyseared you sure about 3G, i’m sure i’ve done it before.
you can get a call (it will come in) depending on which type of cellular tower you are connected. regardless of which type of tower you have if you do happen to get the call it will shut your browser and you cant access internet during the call.
actually @philo, there is also GPS, louder speaker, better earpiece quality. and i know because i had both
@philo In my experience during long calls with my mum even with 3G it never connects. I admit it does look like its trying to load the page but the browser always times out before anything happens.
