Something might be messing with the signal. Any unusal or new devices that emit a signal? Usually this is when the phone gets a 3G signal and then looses it and then trys switching the Edge and then back. There are places in my house that are a pain. Other than that, there could be an intermittent problem from your local tower. I'd wait a couple hours and see if it keeps happening.

My iphone 4 that I have had for a year and a half just started doing this yesterday and hasn't stopped. Every 30 seconds it has a signal and the other 30 seconds it is searching for a signal, no matter where I am and what kind of signal I have. I have rebooted several times and removed the SIM. Nothing has fixed the problem.
Any advice would be great!

My iPhone 4 just started doing this yesterday. Strong signal, then searching, then no signal. Drops all calls. Any help yet resolving this issue? Hard reset did not fix it.

Apparently, this is a SIM card issue.
Option #1 Try removing the SIM card, power down, re-insert the SIM card and power on.
Option #2 This is what corrected my iPhone 4. Swap TE SIM card with another iPhone 4 users SIM, after a few minutes, replace your SIM card into your iPhone.
Option #3 Have your wireless provider replace the SIM card. Should be free.

Thx for the feedback. Went to Apple store and they tried everything that you suggested. I ended up with a replacement phone. The old sim card works fine in the new phone. Option #3 was suggested if the problem reoccurs.

I think i found out the solution. first unlock the phone then press settings then press general then press reset
then reset your network. start the phone back up and go back to reset and this time click Reset all settings. start your iphone back up wait about a min or two and it should be fine. YOUR WELCOME i was about to return my iphone if i couldnt fix it lol but its fixed.

OHHH i have a solution that happened exactly the same to me !
At first it lagged then the next day it keep saying searching ALL DAY !
1. (IMPORTANTLY) - Connect to itunes
2. (IMPORTANTLY) BACK UP Your DEVICE !
3. Restore to factory settings .
4. Your phone will act like it was new .
5. When it says WELCOME on your phone , Do all your setting on your phone
6. When it says Back up as new phone or back up as (BLAHBLAH)
7. I know that you would want to back up as before
8. AFter it dones backing up like before ,
-You should get signal and 3g and reception like BEFORE .
DID THIS HELP?!

i hope this is not a hardware problem... it happened to me recently, ios 5.1. i think every 2 minutes the signal drops from 5 bars to no service. i thought tuning off/on the phone and removing the sim will fix the issue
but i didnt. what i did was i turned the 3g off/disable in the network settings. as i turned it off, the signal became 5 bars again... after a few minutes i enabled the 3g again... and so far network signal is not that erratic
dropping suddenly... i hope the said issue is permanently fixed...
