Signal Search Loop in iOS 5.0.1

So I was one of the unfortunate people that experienced the signal search loop with the 5.0 upgrade. By signal search, I mean the phone would have a signal, lose the signal and show searching, then show no service and then jump back to a signal. This loop from service to no service back to service takes less than 2 minutes which pretty much makes the phone unusable as a phone. I can get texts to go out when it shows a connected signal but that's about it. After the iOS 5.0 update when I experienced the problem I was able to do a restore to get the problem resolved. I updated to 5.0.1 yesterday and now the signal loop problem is back. I'm currently going through the restore now hoping it will once again resolve the issue. Interestingly enough, i also have an gen 1 iPad and it never has had this signal problem. I'm guessing that the 3G hardware in the iPad is different than the iPhone and we have some software problem in the drivers on the iPhone.

My wife has a 4S that was also upgraded yesterday and it's also experiencing the same problem. Please apple, correct this issue, it ***** to have the worlds best phone but not be able to use it.

**Solved**

Hey all -

Ok, so, i remembered that I installed CHOMP on my android device the night that all of this started hapening for me.

I have since uninstalled CHOMP and now use STOCK and HANDCENT. Using my own iPhone 4 on AT&T, I am NO LONGER able to reproduce this crashing behavior using HANDCENT or STOCK - regardless of how large in size the MMS is. I have read on other forums that CHOMP was used as well.

There is just one instance of a person crashing a bunch of phones in a store as a test - and I wanted to see if it was CHOMP that he used.

To add to this soluion, can anyone confirm that they used CHOMP (or CHOMP was used) when you noticed this issue?

Thanks a ton in advance, and hopefully this can be laid to rest.

Matt!

I have had a very similar problem. I turned off MMS messaging, and that worked for a week. Now its back again. Have you found a solution yet?

EDIT: its with my iPhone, not android

Go into Settings--> Location services --> System Services and turn off cell network search and whatever else you can turn off there. Fixed the problem for me.

Since turning off MMS, I have not experienced the problem again.

Knock on wood, I'm still running without any issues. January 19th was my last restore so this is the first time I've gone for more than 30 days without having to restore since IOS 5.x was released. I recently enabled MMS again under settings. Today I received a picture from my droid friend without any issue. I'm wondering if AT&T has made a network change that corrected the problem. I'm still running 5.0.1(9A405) on my iPhone 4.

How about the rest of you AT&T users, have you also noticed a reduction in signal search loop frequency?

I should have knocked harder, looping started again today. So if anyone is thinking about turning MMS back on, beware that there are still possible consequences.

cunnincr, The problem is when it's an android user sent the message using chomp sms to an iphone user. This will send the phone into an endless loop. restoration of the iPhone fixes it
