I have the htc TB. I love it other than the fact ive had MAJOR DATA issues since day one and wondering other POWER users if they have seen what i have. So far: I had my original phone, now i have a replacement with brand new sim card. It seemed to fix the data issues, but they came back during the day today. Basically I am not able to log into ETRADE APP without a NO Data available error. I try to get email and it doesnt sync with email when i send it. I try to log onto the internet and about 50% of the time it will load a page and the other time, it just doesnt (wait forever) usually this is all when it says 4g UP top of the phone. IT IS DRIVING ME NUTS! I switched from Sprint here in PHX because they dont know when 4g is getting active on their system. BUT ALWAYS, i mean ALWAYS data goes through on my sprint EVO when i had it through them with 3g. WHATS THE DEAL ? is it a PHX, az 4g LTE problem? Anyone here in phoenix have the same issues??
