I just got my Droid X so I was planning on txfr my old Droid to my mom on my secondary line since she'd like to try it. I was planning on just killing the data and set it up to automatically jump on wifi at home and and open wifi elsewhere. The new 150MB plan is nice but I imagine more than she'll use for awhile. One option I heard of is cloning the esn from the little samsung knack she currently has. Is this possible or are there any other options besides wasting $15 a month. Too bad the Pay-per-MB isn't so rediculous or I'd get away w/ just blocking data usage.
