Did this by accident, but it is sweet. Put my microsim in an adapter and put into a friend's iPhone 2g that had to be activated through AT&T. Actiavted the phone and put it back in my iPhone 4. Next day I call AT&T and on the ip4 I am still part of the family plan for minutes and text but now the phone is on unlimited data and 200 text messages for only $20. If I get any line activation fees on my bill I will play stupid and have AT&T refund them.
 
I'm sure you're not going to have a hard time playing dumb🙄. AT&T can tell what phone you are using and sooner or later the system will detect the iphone 4 and change you plan accordingly.
 
will only last for few days ... ! they will put you on $30 unlimited plan . in few days/weeks .. been there done that !
