All this has started lately. First were the wifi problems, started with the 2.1, and worsened with 2.2. Sometime recently, my phone's time has started lagging behind anywhere between 10-45 minutes. Since upgrading to 2.2.1, now my phone does not ring when asleep.

So my first thoughts have been that it must be a corrupted baseband. Yesterday, I went though the process of downgrading to 1.1.4 and then upgrading back to 2.2.1. Quickpwned and everything (except wifi) was good--but only for a few hours. Everything is now back.

Anybody experiencing similar issues? Any thoughts on what might be wrong or, how to fix it? Thanks a bunch.

Cheers,

So it looks like the following directions swiped from another thread at least brought back calls ringing when asleep. Note, since my wifi is dead, I used iphonebrowser via USB rather than WIFI/WinSCP...
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

I also found wifi half worked, until I locked the phone again...meaning, it could at least see networks (but not connect).
Let's hope this solution holds.

Still though, my battery life is shit and I have no wifi. Anyone have any luck changing their comm's board? Wnjunkie? Did that come in yet?

EDIT 1: So renaming that file simply causes your phone to never actually sleep, hence the shit battery life. I uploaded a plist that someone posted from a supposedly healthy phone, I'll see how that goes...
