blackberry sim card into a sony ericsson phone?

yes you can, the sim card has nothing to do with the phone itself - just the company. but your sony ericsson has to be from AT&T too.

Ya sure the old AT&T sim will work in sony ericsson w580i mobile only if it is unlocked one else if the phone is locked to some other network provider then it wont accept AT&T sim until you unlock .You can easily unlock your phone using sites like ProUnlocking.com they are rendering unlock code for all mobile models at reliable cost .After unlocking your phone you can freely use it with any GSM sim ....
