Mind Your iPhone’s Baseband before You Unlock
Your iPhone’s reception depends on the strength of your carrier’s signal and the configuration of the unit’s receiver. The latter refers to your phone’s baseband, and you’ll have to note its settings before you unlock your iPhone. The baseband settings of the unlock program and your iPhone should match. Otherwise, the unlock will be unsuccessful and you’ll have to reconfigure the program before you reinstall it. Most users choose DevTeam’s Pwnage Tool for iPhone unlocks because it’ll upgrade the iOS but keep the default baseband configuration intact. You should be able to handle the baseband tweaks so long as you ensure the program and mobile carrier’s baseband matches.
