well the blackberry pearl 8120 is the version with wifi access. I have an 8130 and a data plan and I couldn't be more pleased. These phones are great for social networking, blogging, and messaging through mine. IDK if this is right and I hope someone corrects me but the push email won't work without a BlackBerry data plan so stuff like that wouldn't work and IDK about messengers. Hopefully someone here has a 8120 that can answer your questions more fully. But I hope I helped some.
