I have the walmart t-mobile phone. I got a message saying they want me to update, I assume to ICS from gingerbread, but I'm reluctant to do this. I keep reading some bad reviews about how badly ICS runs on this phone, including some fast battery drains and stuff like that. Also, does foxfi work for those of you with ICS, unrooted? If anyone can confirm that battery power works fine and foxfi works fine on ICS, then I will upgrade. Thoughts, advice, welcome. :dancing2:
