    Restored yesterday, on pure 4.2.1: 97% in the morning.

    I did a fresh restore last night and re-jailbroek with B4. My battery life has been better today also.

    I wish I just ran the B4 jailbreak over the B2. lol
    Ha, sucks. I literally took a deep breath and my anxiety level rose a little when I was doing the B4 over the B2. I almost flat-lined when my phone was stuck on the little skeleton startup thing when it was done. I just did a hard reset and then it booted up like normal. Literally almost freaked out. haha

    "Restore as New device"... (time consuming i know, but worth it) then jailbreak with RC6 Final. i did this last night and it has worked out great, as i was dealing with a little battery drain from running on top like your considering

    once again, not sure why the jailbreak itself would cause any type of battery drain.. i loaded all the same apps/tweaks as before. odd

    let us know what you think

    BLiNK, I'm still not thrilled with my battery life after JBing and then putting b4 on top of b2 (I know I got the phone doing more stuff than before -- way better stuff though) but still the life of the battery is not what I would like. So you are saying to Restore the phone as a new device in iTunes first. Do you then Sync it in iTunes to get your stuff back, and then JB using the most recent GP build? Or JB it then Sync?

    My iphone is a 3GS running 4.2.1 and wasn't previously JB. Started with b2 version of GP then I did the b4 build on top of that due to claims of better battery life.

    Next question is I assume that I need to make notes of what Cydia stuff I've installed (and purchased) so that I can redo them after the JB and sync? I assume that Cydia keeps up with my purchases (biteSMS, etc)?

    I can say that my battery life is slowly getting back to what I consider normal. It's been a week and a half since I JB, and I am now getting home with 40% battery. That's up from having to charge it on the way home. It is coming along nicely. I'll just have to wait and see if I can get home from work, 12 hours after unplugging it and be at 70% like I used to.

    correct. do not restore from back up at all. the only time consuming part should be if you have multiple emails set up, in which case take notes

    in fact, right after i "restored as new" i jailbroke right away just in case something were to go wrong.... then go ahead and sync your photos, music, apps etc

    My iphone is a 3GS running 4.2.1 and wasn't previously JB. Started with b2 version of GP then I did the b4 build on top of that due to claims of better battery life.
    i did the same thing and at the time.. it seemed ok but every time "i restored as new" it got better

    Next question is I assume that I need to make notes of what Cydia stuff I've installed (and purchased) so that I can redo them after the JB and sync? I assume that Cydia keeps up with my purchases (biteSMS, etc)?
    yes, any apps/tweaks you have bought will recognize your device and then can be loaded back without any issues

    typically, when i do any type of restore i will hand write all my apps/tweaks from my packages section in cydia and manually load them. some people use backup apps and such but i ran into issues in the past

    ****

    i have noticed a BIG difference every time i "restored as new" in regards to my battery life. i am glad that this is the final release of greenpois0n (4.2.1) as my device is set up perfectly..

    after you do this please let me know how it worked out for you

    I JB with GP RC6 and my standby battery life sucked. After 2 days, I restored back to factory and battery life is back

    Thanks BLiNK. I appreciate the very detailed response. I'll give that a try as soon as I can dedicate time for it.

    I did find an app called 'AptBackup' that claims to restore your Cydia apps. Free so figure I'd give it a shot but I definitely will take some notes on what I have already. thanks again and I'll post an update.

    Ok I just ran gp final on top and it seems to be working better. I got 7.5h use and 17h standby today so with all the same apps except my3g this is about right for me. I'm not saying it will work for all but I'm good with my battery life now. Thanks if I hit any other problems I'll restore from new.
