Ok so i found another loophole for people who do not have iphone 2g and wants to get $30 unlimited data.
This is what you will need. You will need any dumb phone's IMEI number.
I just did this yesterday night and it happened within 3 to 4 hours.
First, call 611 from your phone and enter all the necessary info and then press 0 to connect to a rep. Tell that rep you need to activate a different device (dont worry, you r not) on the line you are calling about. They will ask for the IMEI number so give them the IMEI number of a dumb phone. Dont worry, you dont really need that phone with you. Once they "take off" iphone 4 from your account, it automatically takes off data plan connected to the iphone. Now, before you hang up, tell the rep that you want to add $30 UNL web,text and email plan on that line, They will gladly add that for you. Once that done, hang up and just chill. Just keep that sim in your iphone 4. make a call or two and wait for 3 to 4 hours. You will get a text saying that you are using an iphone and your data plan has been changed. Now this will add UNL data for iphone for $30 and UNL text for $20. if you do not need text like me, just log into OLAM and take texting off like i just did, And now you will have UNL iphone data $30 plan without even getting an iphone 2g.
If anyone here wants to get a dumb phone IMEI, i have it. just PM me and i will help you out...
