    Default [Help] iPhone shutting down after 2.1 QuickPwn

    I've updated my phone to 2.1 via itunes, then pwned via quickpwn selecting the options of installing cydia, installing installer. Now my phone shuts down randomly, I mean it doesn't just go off, but you see a normal shut down, the black screen with a spinning circle in the middle to be detailed. I've noticed that this is only happening when I use it 'as a phone', when the SIM is unlocked and there is probably gsm traffic or something...
    Help would be greatly appreciated on this problem, because now I can only use it as a mear ipod... ;[

    This is a problem many people faced when they used their 1.x.x back ups on 2.x.x

    After u restore did u use the itunes back up????

    SOLUTION - DFU restore to 2.1 and set up phone as new
    MacBook Pro OS X SNOW Leopard
    iPhone 4 16GB iOS 4.2
    iPad WiFi 64GB iOS 4.2
    BlackBerry Curve 3G (9300)

    I've restored to 2.1 and pwned, then it was fully charged. It worked ok until now. Usage shows:

    Usage: 30 minutes
    Standby: 4 hours, 12 minutes

    Worked ok at that time, then it shut itself down after sending an sms, I turned it on, entered the pin and after a few seconds it shut down again and so on... If I don't unlock the sim it works... The battery at that time went 60% to 30% or something at the shut down...

    Another update...
    Plugged in the USB and the battery is kinda back over 50%, just tried deleting com.apple.SystemPowerProfileDefaults.plist and doing a hard reset. After that I see my battery like 60% or so... Then I unlock the sim, send an sms, make a call, browse some big sites (which eats more power over wifi) and send out another sms, bang, iphone shuts down... After it shut down, I start it up again, the battery looks like 25% or less, unlock the sim and I see a black screen with a spinner indicating that the phone is shutting down... Ok I'm desperate here

    I have exactly the same problem. During 3 days my problem seems to be solved but I'm having it another time. I tried to reflash baseband and bootloader but the problem remains. ┐Options for that?
    The strange thing is that in fly mode the iPhone don't go off.

    Regards

    Similar problem happens with the Wifi. After downloading something in Cydia or Installer, the Wifi just stops connecting.

    I have made a downgrade to 1.1.4, downgraded baseband and restored the firmware to 1.1.4 to clean the phone. After that, I restored it to original 2.1. Now I'm restoring it to a custom 2.1. I hope that will be the solution but I'm not sure..

    EDIT: Hasn't worked

    Regards
