Anyone else having problems with their 3G dropping? I bought my first Droid 3 on the 14th, worked perfect but battery was horrible. Took it back a few days ago, got this one, battery is a lot better but lately, I can't keep my 3G up constant to save my life. Any ways to fix this or? *Note - Switching to airplane mode works.. but then after about a couple of minutes, it goes back off. Same when restarting phone, too. Also, I've tried updating roaming.
