I've had success with handoffs from wifi to Unicel (at home) and vice versa. However, where I am now, there is no TMobile anywhere and a choice of SunCom or AT&T. Unless I lock it on TMobile during one of the UMA cycles it will constantly switch back and forth from TMobile-hhonors to Suncom-hhonors and lose UMA and then a few minutes later, switch back to T-Mobile-hhonors/UMA again. It's just a little strange and thought I'd post on how to make the UMA "stick." It's just that UMA handoffs don't work when the device is in Manual.
