I would stay at 4.1 for now until the release of 4.3 and hopefully a better jailbreak of Pwnage tools or Snowbreeze , only then i will go up to 4.3 and do the jailbreak & unlock.
My iphone has no more battery drain issue.

ok I got it all updated to 4.1 now my problem is I cannot get most of my apps to load, how can I tell if it is still JB? I'm thinking this is why just not sure. On Cydia it shows in light green SHSH: iOS 3.1., 3.1.2, 3.1.3, 4.0, 4.0.1, 4.0.2, 4.1. Do I need to restore with Tiny umbrella? I found this, just want to be sure prior to doing anything

To restore simply press “Start TSS Server” then open itunes, hold down shift(windows) or option(mac) then press restore (tiny umbrella only supports restore not update). A windows will open where you can choose the firmware that you want to restore to. You can download firmwares from here: IPhone Firmware Download Links - ModMyi - Wiki or here iPod, iPhone and iPad Firmware Download
It is best to use a browser other than internet explore for this as internet explorer will download the file as a .zip file when it is supposed to be .ispw. If that happens simply rename the extension from .zip to .ipsw. Firefox and other browsers do not have this issue. Also if you get a 3002 error put the iphone in dfu mode first then try the restore. To put it in dfu mode: plug in the iphone, then hold the power button and home button together for exactly 10 seconds, then release the power button while continuing to hold the home for an additional 10 seconds or until your computer and itunes recognizes it. iTunes will see it as being in restore mode, the screen of the iphone should be all black.
