Gonna call Sprint today, also running 21079 PRL with nothing else out there - Noticed 3D is def not as good as 4G in terms of 3G speeds, Its dam slow even with full bars, I have never had an issue with loading pages on the go, and now it takes awhile - but i will add this i think on the flip side the wifi is faster than 4G which is interesting -
Been thinking about returning for Nexus S for the past couple of days based on camera defects (2nd Evo 3D with green tint to pics both 2d and 3d and video camera - mostly high light 2D, low light 3D low light videos, and now signal strength is bothering me
**interestingly enough though most people have been having success with the profile and prl updates improving quality, i noticed something through all this, if you go to settings and manually update profile and prl thats one thing, BUT going into the dialer and hitting *2 and realizing that no matter how many times you update the profile through settings, there is a profile update notification in the Sprint page that loads up maybe the real way to update, I noticed my signal bars increase afterwards ....
***Another thing i noticed if using Dolphin HD is to download the add on for it called faster browsing or something to that extent which helped as well***
