the only issue that should show up is MMS (Multi-Media Messaging)...the i530 was not an MMS capable phone...you might have to call in to Care and have them correctly provision you for MMS...you might have to register the MSN from the i580 to be able to receive/send MMS...if customer care gives you a tough time just tell 'em to dummy the MSN out...they will know what that means....
also a couple of other Nextel related sources to bookmark:

Hope this helps!

I went to and signed up for those forums and from the "howardforums" All I get told is my threads are in the wrong spot or my thread gets locked or SEARCH. I searched and when I cannot find my answer they blow me off. Really not friendly folks.
I went and signed up for "meogee" and it wont let me start new threads due to a registration error on their end. When you sign up, you are supposed to get an email to activate the account and it never comes.
Also, Marshall how come you wont respond to my PM's?
