Trust me, the no service problem will come back anytime later.
At least not immediately after you restore.
iOS5.0.1 doesn't fix the said problem.

No luck. I could confirm that 5.0.1 not solving the no service problem. Problem recurs today!

U guys on 3g or not? For me i have no problem, and i off my 3g unless need to surf faster..

No 3G. It randomly hit phones anyway, my brother who has the 32GB iPhone 4 with Digi do not have this problem.

Nop, 3G is off.

My 3G is off, bluetooth is off, wifi is off. Tell me what can I off some more? hehe

Off the phone and exchange for a SGS2. I am only staying with the iphone now due to the apps.

I am not a big fan of Android apps.

Oic.. Luckily i dont suffer the problem both on my iphone 4 n 4s.. Both 5.0.1 n wondering what is the cause..

Highly suspect some conflict between hardware and software.

Yeah...each time need to restore waste me at least an hour

I have done fresh restore to ios 5.0.1 and will test this week to see how the signal issues. If is working fine will let u all know. Tried restore iOS5, unable to do so only can restore to 5.0.1

Ahh I was just hit by this bug 5 minutes ago =.=. Using iOS 5 with semi tethered jailbreak. Suddenly my phone was in searching searching.

Tried to respring my phone via sbsettings. Managed to get maxis line but cannot call in or out. I removed my sim card, didn't work also because it still shows I have Maxis line.

Following that I respring without a simcard, it shows no sim then I inserted my sim still showing no sim =.=.

Last I respring my phone with sim, it shows Maxis line. I turned into aeroplane mode, turn on 3g and data then magically it came alive. After it was working the phone then ran all my previous calls and misscalls. Now everything is fine gonna monitor it.

I did a fresh restore .. no restore from backup on my 3GS .. still have problem .. I believe there is a bug in ios5.0 and 5.0.1 .. bad thing, I couldn't revert back to 4.3.3 .. grrr.. getting the recovery mode loop ..

Tested the network coverage on the way home yesterday and it works fine. No service drop/signal issue.
But i realize that the problem happen when I open my foursquare app... so now I hv remove the app and phone work fine...

Don't have 4sq app on my phone still problem occurs. But i highly suspect is the activation of imessage thats doing it, since my bro, who never activates imessage doesn't have the network lost of death.

My friend and I both on iPhone 4 and upgrade iOS5 at the same time; we both have iMessage activated.
My iPhone suffered from this problem twice already (1 restore in between)
However, my friend's iPhone still working fine until today.

This problem really happens too random.
Need more observation and investigation.
Since you suspect its iMessage causing problem, have you tried turn it off and see if problem persists?

I have turned it off on mine, problem's still there.

Come on guys let flood Apple with our complains!
Although they might not even care

I had activated it before. But this newly fresh restore still haven't done anything. So far so good. Cause i can't even think of anything else would make my phone potentially targeted by the network lost of death.

So my hypothesis is any activated imessage users, no matter deactivated in the future or not, will increase the probability of network loss of death.

Need more testers to my support my hypothesis
