try this...go to Settings - More settings - Mobile networks - Access Point Names {on lower left settings "Reset to default"}
(if you haveT-Mobile Teathering + T-Mobile US -then T-Mobile Tethering with disappear and will work afterwards)
I almost posted this in post 1, after a clean install, I didn't notice that problem...It's mentioned in the MOD's Thread Orig MOD's POST has more info
If this becomes big problem, I know TrevE Mod v3.2 betav5 will work fine. I will post link up later in Post #1 as optional Working HotSpot Hack!
Thanks for quick reply.
I did do a clean, full wipe install as directed, and went into the APN settings, only saw the T-Mobile US apn, reset to the default, and still a no go. Getting upsell redirected.
