my phone is 1.1.2 OTB upgraded by itunes to 1.1.3 so got unlocked. then i unlocked through the source www.desbloquiobr.com and now it is 1.1.3 with 04.02.13 BL 4.6.

is there a way to have the latest baseband and still keep the iphone unlocked?
actually is the latest baseband in anyway better than the 04.02.13?
