in theory the os can multitask. its basically a variant of the bsd kernel and

so on used in osx. jailbreaked current gen iphones multitask. but apple have

but a limit on sdk based apps, claiming battery life reasons. instead, if one

wants to liten for im traffic or similar, one sign up with a apple messaging

server that will pass this on to the individual phone, kinda like a push mail

service.
so for a im client it will be:
im network interface at app makers place -> apple message server -> iphone,

where it will show up as one of 3 kinds of onscreen messages.
