Upgrading to ios 5 with baseband 06.15.00
Well, i dun goofed.
I got uber frustrated when bringing my iphone from canada to new zealand. The phone companies wanted to charge me a ****ton to buy all this new crap that i didnt want so i decided to unlock my phone! Unfortunately i was on a baseband that couldnt unlock. After a lot of ****ing around I finally got it but to do it i had to up my baseband to 06.15.00 on ios 4.1.
Now I kind of wanted to upgrade to ios 5 when it comes out and gets jailbroken but i was wondering if this will be possible with my current setup and if so, how. There was some warning somewhere that with baseband 06.15.00 i wouldnt be able to change the firmware or something. In my frustration i ignored it stupidly.
Thanks a ton!
EDIT: obviously i would like to be able to keep my phone unlocked/reunlock after upgrading.
EDIT2: Also, It would be awesome if i could keep all my files. Im assuming this isnt possible but if there is any way, please let me know
