Hey, sorry, this seems like the kind of thing that's already answered, but 30 minutes of searching this site and Google turned up nothing so... Any way, my friend wants to get an AT&T phone. My other friend has a Galaxy S on T Mobile, and he apparently is getting the dumb phone unlimited data plan with the T Mobile version too. He said he changed the IMEI by deleting a certain folder after rooting. I found some tool on here for changing Samsung IMEIs, but there's not really a clear guide. So what I want to know is:
How do I change the IMEI on the Galaxy S?
Will this work on AT&T? (ie, would my friend be able to get the 10 dollar dumb phone plan on it?)
If I found some cheap one with a black listed IMEI, would changing it make it usable on AT&T again?
