verizon iphone 4 4.3 firmware?

[Verizon iPhone 4]

itunes just made me update to 10.2 im assuming thats for the iphone 3gs and gsm iphone 4.... i was reading at apple insider that verizon iphone will also eventually get the new iOS 4.3 that means we have to update right? then downgrade back to 4.2.6 to re jailbreak? or what will we need to do to keep our phones jailbroken? i know u need tiny umbrella to restore your old firmware... just curious thanks

Just dont upgrade untill 4.3 is fully untethered? you never HAVE to upgrade. theres always a choice.
