Problem reoccured on the 3rd day (not counting those days where i switch off the phone for my trip). Reset network settings but no avail, a restart is needed. The problem manifested now is in the minor stage where a restart will solve things which will probably progress to the chronic stage where even the network is showing maxis, but the phone won't ring when people call in.

Probably gonna restore again when that happens, now to avoid lifts to prevent network lost. 

No guessing. It doesnt work.

I actually install semi tethered right after I JB...but the no signal become worst...and no way to make any calls even with Signals. I dunno if this gotta do with semi tethered or not but after I did a restore, I didn't install it again.

Anyway, so far it's ok. Even after no signal at some areas it does search and pickup the telco. Can make calls also. Hope it remains ok
