i'm pretty sure its an IOS5 bug.
me n my wife both using iphone4, one is on IOS 4.3.3, and another is on IOS5.
problem only occur in IOS5.

Yes, i tried installing semi-tethered again and it worked....probably i got unlucky the first time...so i tot the semi tet was the problem.

Finally a coverage by engadget! Great. Now can apple faster respond to this issue?

apple need to cover this issue.. and fast!!

That is referring to WiFi connectivity problem...
What mentioned in this thread is the phone signal problem... which I sees it more serious one

I believe its in tandem with our signal problem here.

I dunno abt other ppl but my Wifi (ios5) seems Rock solid!....better than lets say 4.3.1.

this "no services" issue is getting worse..
now even reset network and reboot won't solve the problem..

these is getting annoying already.. stupid

Uh oh, the problem crops up again after few days of reboot. Same case as others.

setting>general>phone>sim>off

have anyone try these, help?

It wont work..I even take out the sim phyically a few times...no go..

this is by far the worst bug ever since i'd be using the 1st gen iphone.
as some of the forummer said, iphone don't act as a phone anymore..
what's left is just 'i', and no "phone"...iDIOT

hi all, as I see that everyone has the issues of whereby the network cellular dropping to NO service or searching issues and my iphone 4 had the exact same problem. I have tried several options like restart the phone or reset the network settings, all of the steps does not work.

I have found one temporarily solution is that if really all the above mentioned steps does not work, try this method as below. Before doing the below steps, PLEASE MAKE SURE SYNC UR IPHONE to ITUNES 1st to backup before doing the below steps as I'm not held responsible for any data/apps/contact or etc missing after doing the below steps. After then you finish resetting it to default, your main screen wallpaper is back to apple default wallpaper and is like setup a new phone again and the nice things is that ALL your apps,contact,songs will still be intact.
Try it and it works for me as temporarily solution while waiting for Apple to release new firmware.


Go to Settings->General->Reset->Reset All Settings

P/S: Make sure select RESET ALL SETTINGS

AND NOT ERASE ALL CONTENT AND SETTINGS

sometimes i also facing this situation , i hope the next ios fix this

It's weird when I'm not facing any of the issue. Other than signal loss when holding the phone using my left hand...

funny thing is.. it comes n goes.. when ur really using ur phone (calls etc..) then it happens but when ur gaming ipoding (if u may) it retains it signal... wtf????!!!

^What he said Just the settings and stuff are reseted but ur apps/msgs are still intact, well i guess its the best way ... for now.

Try restoring back your phone.....it did happen to me also. after i update to ios5.01 , i cant even call out and receive any call.....

The "reset all settings" only work once, i noticed. The second time does not work, restarting doesn't fix the problem either. Have to resort to full restore now.

5.1 beta is out. If the full 5.1 doesn't solve this shit, i am gonna trade this shit phone off for a droid.

sell to me cheap cheap la hehehhe
