question about bootloader

[rimrocka0834]

I am running a jailbroken phone on software 1.1.3 that was jailbroken with ziphone. To my knowledge i thought that since I am an ATT customer and I dont unlock my phone I dont have worry about all these baseband and bootloader issues am i correct? The reason I ask is because I want to goto a completely stock version of the iphone as if I was going to bring it to apple and I was wondering which method to use. Should I use the ziphone refurbish option then put my phone into DFU restore mode and restore it to 1.1.3 then restore to 1.1.4. Or should I not run the ziphone refurbish and just DFU restore to 1.1.3 then restore to 1.1.4. I guess my real question is how to goto a completely stock version like OTB iphone running 1.1.4. Thank you in advance.

PS. my modem firmware is 04.03.13_G and i bought my iphone on oct 29 2007. Thank you.
