How to spoof IMEI because AT&T forces $25 dataplan on any smartphone (even sans contract)

Q: How can I change the IMEI of a smartphone to spoof a non smartphone?

A good friend is willing to give me as a birthday gift an unlocked Blackberry 9800 smartphone because I like the keyboard. My 2-year non- smartphone contract expired with AT&T long ago - so I'm only buying cellphone (no data, no texting) service from AT&T at the moment.

However, according from my calls with AT&T Customer Service, if I plug my AT&T SIM card into any smartphone (even if I borrow a non-AT&T unlocked smartphone), AT&T will automatically charge me $25/month for a dataplan (the higher of their two byte-charge dataplans, BTW).

I do NOT want a dataplan. I just want the nice keyboard of the smartphone. I'm not even considering buying an AT&T-subsidized smartphone so I won't have to sign any contract whatsoever with AT&T. Yet, AT&T says that as soon as they "recognize" the IMEI of any smartphone, they add the data charges - automatically!

I feel that's criminal (and I guess one option is to go find another cellular supplier) ... but my question is simply technical (not legal).
