If the SIM card is properly in it's place, then you should read the following:
-
since the phone is getting a weak signal and loses the signal within a few seconds - i would say that there is a problem with the antenna area (connectors/antenna)
+
Since the iPhone is getting a weak signal and loses the signal within a few seconds, I would say that there is a problem with the antenna area (connectors/antenna).
-
if it would have full reception - but loses the signal within 5 to 10 seconds - it would normally be a defective power amplifier or a broken antenna switch (most likely the switch would die first when a phone is dropped)
+
If full reception is available, but the iPhone loses the signal within 5 to 10 seconds, it would normally be a defective power amplifier or a broken antenna switch (most likely the switch would die first when a phone is dropped).
-
the "no service" message in those two cases is normal(!) - the phone receives the signal but the bts (Base Transceiver Station) does not recieve a signal from the phone (something like a handshake) - so it does not "lock" the "cell" to the phone and goes on - it simply doesn't see or hear the phone - and that was the short explanation why you get the "no service" message

if there is nothing to see from the dropping and the phone is still under warranty - go to apple!

-
if not, open the phone and check the connector between the dock conector ant the logic board - maybe it's slightly dislocated
+
If not, open the phone and check the connector between the dock connector and the logic board: it may be slightly dislocated.

wut you wrote that you checked the connections - that could mean that the antenna is defective - but check everything again - checking is better than buying a new part ;-)
