anyone else having this problem? using 2.1 under caulkin's kernel. it seems like I can kind of overload the phone doing too much and the mobile network connection on my phone will disappear completely. this is while downloading something that may download too fast, sometimes it happens loading .GIF images too. I'll have to restart the phone to get the internet back. this happens no matter if I'm using wireless, USB or bluetooth tethering. any ideas? thanks!
