have this unlocked on tmo usa and wondered if anyone on here had experience withupgrading radio version on it... I here the 1.54 works well on att but need feedback from tmo users in usa... Phone currently has 1.16
I was using 1.47 for a long time and it worked fine on t-mobile. Yesterday I tried to upgrade it to 1.54 but no luck. It seems not able to connect to t-mobile or you have to wait for a long long time. So I ｎｏｗ ｃｈａｎｇed to 1.51. Works fine until now.
