Do you use your phone as a hot spot? If so how long does you battery last and does it work well regarding speed?
No I don't, I did when I was jailbroken with MyWi, never noticed any major decrease in battery life.
but speaking of sprint data speed, my girlfriend's father has the hotspot on his phone, he cancelled the Internet at his house and I thought it was a stupid idea till I tried connecting with my computer both at his house here in souther Chester county and at the beach, in ocean city NJ. The speed was just as good as mine, and with another computer connected to it (my girlfriend's laptop) So to me it's just a matter of how and if they gonna do early upgrades like AT&T does, that is all.
voice quality AT&T as never been good, the only reason I've stayed with them, beside the fact that they were the only one to have the iPhone, is their 3G speed, which lately has been slow for me.
I'm not in love with AT&T like some people here are, so once again, the sprint idea sounds appealing to me right now.
