ok, thanks to the advice of amageus, my 3G issue has been fixed. I was having a problem, where my data would cut out about 15 minutes after my phone went to sleep. Sometimes the 3G would come back right away if I woke the phone up, other times it would not and I would have to reboot (the airplane method rarely worked) Turns out...under Settings > Battery & Data Manager > Battery Mode, the default battery mode is nighttime saver, which turns data off 15 minutes after your phone goes to sleep... I selected Custom and it now no longer turns my data off after 15 minutes. I feel pretty stupid considering I went through the hassle of flashing the .893 update hoping it would fix my issue and it turned out to be a stupid default setting... I'm hoping that a lot of the people with 3G issues can also fix theirs this easily.
