Well we just went to Las vegas and i had no phone service. Nothing at all. I called Sasktel and asked WTF. They said that on 2.1 at least you had voice calls but with 2.2 upgrade there is no roaming at all in the US. Of course they blame it on Samsung. They are hoping for a fix in a couple months. What a crock of s#$%#t. They should have emailed or wrote a letter to all of their clients. im going to call tomorrow and raise hell
