Upgrading to 4.1
I have an iphone 4 which I originally jailbroke with jailbreakme.com. I have never updated since so i'm running 4.01 with baseband 1.59.00. Is it possible for me to upgrade to 4.1 which was the gamecenter and hdr update, or do I have to wait until the newest jailbreak is released?
Did you save a SHSH for iOS 4.1?
If not.. then no
i remember having cydia do this for me, so what is the process to go to 4.1?
You need to check/confirm. Depending on when you let Cydia do this for you - you may or may not have managed to back up a 4.1 SHSH in time.

NOTE: this baseband update prevention DOES NOT WORK for a restore to 4.2.1 - do NOT try this.
