The disappearing network connection issue is killing me.
Its been happening frequently.
One moment it'll be fine, suddenly i'll loose all connection (GSM & 3G) temporarily. Then GSM would restore, but i'll need to enter and exit flight mode for 3G to restore.
if you're rooted you can try these tweaks by adding them to your build.prop in system folder

http://forum.xda-developers.com/showthread.php?t=1210341i always put these tweaks everytime i flash a rom especially checkrom revolution. i dont know why but my connection sucks with checkrom's modem+tweaks, had to remove their network tweaks and apply mine. if not my connection will work for 1 min, then hang, need to off network data and on back only can work, for 1 min then jam again
