Can be on and detected by iTunes? Try do a fresh restore. If problem still there even after restore,better send for warranty claim.

Thanks alot, will try and see

May i know why is this related to battery? I mean my iphone 3gs has the same problem too. Keep restart by itself

I had many customers faced this issue before. Fixed by changing battery only. Other components are lil bit non related. Parts to test is just the battery.

Definitely no problem

hi i have a problem with my iphone 4 ,after i upgrade to ios5 the phone cant activate. it say only compatible sim cards from supported carrier may be used to activate iphone.please insert the sim card that came with your iphone or visit a supported carrier's store to receive a replacement sim card..before this i use ios4 the sim card can use like usual..can someone help me with this?

The set is from which telco? Still under warranty?

iphond 4s cannot receive and send messages....when people call in no notification on my phone even tough it is ringing on the other side...can help? i got two ip4s with the same problem dunnoe its' hardware or software bug...

Your 4s shows full signal bar? Which telco you are using with? When did it happen

Hi people..

Anyway a friend of mine is having the same problem. Her phone can't send/receive messages. Can't make/receive calls. When someone calls, it rings on the other side but nothing on my her side. Weird thing is that while no texts can get through.. she gets texts from those 66XXX numbers. She said she can still surf using the phone.

After I told her to restore her phone.. it worked fine. But then a few weeks after, maybe 3 weeks after it happened again. So although the problem can be solved by restoring the phone.. it's kinda crazy to be doing it every time right?

Her brother and another friend said there could be a problem with the sim card. Maybe the person cut it wrongly or something.

It kinda make sense that it's a sim card problem as she can still surf using WiFi..

Any ideas people?

Thank you in advance

Why suddenly wifi, blue plus network not working? Water damage or what? Seems like a motherboard damage to me.

Story : suddenly my iphone shows 'Please Connect to iTunes' and i did jailbrake and all those to recover but it failed. So i send my phone to one of forumer and after few days, he said can't be recovered. After that my friend help me to restore less than a day but according to him, there is a hardware that has been taken out caused the phone to lose its ability to use wifi, network, and bluetooth.

So i was wandering is it really true? Where can i buy that hardware?

Whats your baseband numerics? You just dont buy motherboard parts. Even its available in the market, will be quite pricey and you will need to equip yourself with some knowledge before repairing it.

I'm not sure though. Might send to someone who knows how to do it. :\

Is that locked set ?

Since you can enter home screen now, check settings> general > about > model & modem firmware.

I think he just screwed up his baseband chip. BTW they (the shop) can't take part of the hardware as it come as 1 piece unless they swap the logicboard (something like the phone motherboard) all together.

Hmm...seems legit. Last choice is to replace motherboard? But got reply said motherboard and the wifi/bluetooth/network hardware is separate.
