3gs activated with official sim battery drainage

[Makaveli07]

I had a tethered jailbroken 3gs 4.2.1 with ultrasn0w and SAM installed. SAM was saying that the phone was WildCardActivated but the battery was still draining very quickly while on standby. I did some research and found out that there was an alternative to using SAM which was activating the phone through iTunes with an official sim that the phone was locked to. So I decided to do a fresh restore of 4.2.1 and borrow the official sim to activate the phone through iTunes which I did successfully. Then I jailbroke the phone again and installed ultrasn0w 1.2 through cydia to unlock the phone. I'm noticing no change in the battery drainage issue. Battery is decreasing roughly 2% every 10 mins while on stand by.

Can anybody help me or give me feedback from their experience?

Yes, this is the issue, nothing much can be done, it can go flat the next morning. It is due to the combination of Pwnage tools and redsn0w. If you don't need unlock, restore to stock 4.2.1 and jailbreak it with redsn0w.
OR if you have 4.1 blob, restore to custom fw of 4.1 to preserve your baseband.

Did you restore from backup after you restored and activated with a legit sim?

After activating by official carrier SIM card, you should connect iPhone to internet via Wi-Fi, before you jailbreak it, this step will get your phone a valid push certification. Then no battery drainage any more.

I tried but got the error 1015 as I updated the baseband... Eventually restored with a custom firmware.

The battery life seems reasonable when I turn off wifi and cellular data. But I just noticed that the push notifications are not working, with this iPush test app. Does anyone know a way to fix it?

I just did this whole process on a 3GS on 4.2.1. After you activated with the official SIM, did you then reboot, install ultrasnow, install non-official SIM (T-Mobile for me), then reconnect to iTunes? I received another 'Phone activated' message after this. My battery performance is normal and everything is working (push, YouTube, etc)

No what I did was:
1. restore to custom firmware
2. activated it with official sim
3. installed cydia with redsn0w while in DFU mode
4. put the phone in DFU again and booted with tethered
5. installed ultrasn0w and thats it

Well, putting into DFU mode again to boot tethered wasn't necessary. After all that, and inserting your non-authorized SIM --- connect to iTunes. I got a 'waiting for activation' for a second or two, then the second 'phone activated' message. The last one after the T-Mobile SIM was installed.

Note: I didn't do any iTunes sync, or restore from backup, nothing within iTunes.
