So I've noticed this problem on a few GB roms (not just MIUI). I've noticed a lot of threads popping up about "keep losing 3g" etc...What I have realized is that with my phone/rom/kernel setup, i'm not "losing" 3g, but more so I keep getting logged out of Google (or something like that, i'm not sure though). What happens is any time after I make or receive a call the "3g" and "signal strength" icons are both white. But, I can still use the internet and send/receive text messages. As soon as i try to use the market though i get a message "Please check internet connection and try again." So, I turn airplane mode on then off and viola! My "3g" and "signal strength" icons are now green again. So i would assume that unless they are green I cannot use the market or sync gmail etc... My question is, has anyone else had these same issues? Or are they loosing 3g altogether (i.e no internet connection at all)? I've reverted to MIUI 1.3.25_2.2 for now until something is done about these little GB issues/bugs.
