An easier repair than I anticipated. My advice is once you get the back off, take a minute to study the orientation of the battery connector and the small black ground clip underneath the top screw; it will inevitably pop out of position when removing the battery thus requiring realignment. Go slow and use minimal force when prying both the battery connector and battery. After powering on the phone, I too had the problem of acquiring a cell signal. After five minutes of the phone displaying "Searching," I did a reset (holding sleep/wake button and home button simultaneously) and when phone powered back on I immediately received a signal from my carrier. Looking forward to greater battery life between charges.
