sprint mogul to att fuze

[adventure95004]

ok, I may have to go to att for "work" . I am using a mogul with sero plan and run everything at home and on road through my wifi router, laptop, ipod touch with skyp, download music and movies, and even occasionally xbox when my son stays with me. No problems with sprint. I like that I can do what I want with the phone, but I hear "stories" about att restrictions.
cost wil be about the same with my company discount on att, just not unlimited mins.
I don't see much good or bad for att so anybody with real experience on att
thanks andy
