This is true... Only bad side to this is when you're on GSM/EDGE and you get home and goto UMA, the minutes still count against you until you re-initate the phone call. That's where grand central comes in for me and I just press "*" and transfer call over to my home phone.
Love the UMA though, seems wifi is in alot of areas I go, I've just never looked for them like I do now..
