Not immedialte, as I don't plan on selling until the iP5 comes out, but I do have a few questions about selling a jailbroken / unlockable iP4. All of this assumes that I restore the phone as new to whatever iPSW and re-jailbreak (so none of my contacts, etc. are on the device) Is there any point in keeping my 1.59.00 baseband? My thought is that the new owner can downgrade to any firmware pre-iOS5 and have an unlocked iPhone if needed. Don't see the harm in leaving the baseband at 1.59.00 - thoughts? Does Cydia identify the device, or go by user account? How will this effect the new owner? Will the new user be able to fetch blobs from Cydia to restore to older firmwares and install/use packages previously purchased by me? Thanks for any feedback - I just want to get a more complete understanding of this so that I can set things up to be the most beneficial for the next user.
