Hi...
How much u paid for the comm-board and how u got it replaced....

Mine is week 49. Maybe it's a whole stock of boards that have the problem.

1.1.2 OTB --> 1.1.1 --> Jailbreak --> 1.1.2 --> Jailbreak --> Turbosim with Claro (Brasil) --> 1.1.3 via iTunes --> Ziphone --> Battery Drain problem --> WinPwn to 1.1.4 --> Bootneuter back to 4.6 BL (still with battery drain problem) --> Lived with that for some time --> Restored to 2.1 --> Unlocked with Bootneuter (dead wifi, sometime don't receive calls, crazy clock) --> Sick with this iPhone (will buy a Black Bery next year)

Replaced SMS ringtone

You can get the com board from ifixit.com for about US159 and get someone who knows how to fix it done for you.

I just see another talk about this software: install from Cydia the Insomnia app, and evaluate your battery performance.

Insomnia is an iPhone native application that, when enabled, will prevent the iPhone from sleeping, thus overriding its default behaviour. This allows background applications to continue to run and WiFi to work long after the screen has been switched off.
(The iPhone's default behaviour is to sleep 30 seconds after the screen has gone off, when not docked and charging that is).

Hope this information can help????

Did an update to 2.2 solve these cases?

nope, not in my case it didnt anyway. i have ordered a new phone through insurance... think mine is officially borked.. wifi dont work at all.. now this... screen is cracked lol.. defo time for a new one!

quickpwn----->www.quickpwn.com

don't know if posted yet but i found sollution on the net on macrumors for problem not ringing when phone is locked.

1. OpenSSH/WinSCP into Iphone then go to:
\System\Library\SystemConfiguration\PowerManagemen t.bundle

2. Find the file:
com.apple.SystemPowerProfileDefaults.plist
Then rename it to:
com.apple.SystemPowerProfileDefaults.plist2

3. Reboot your phone

I tried and can confirm this is working sollution
