Hello Guys Good morning or afternoon! I have an iphone 4 which is my mothers and i got an iphone 4s for myself. I have a dilemma about the UNLOCKING or Flashing of the iphone 4 and 4s i got my sprint carrier me and my mom we pay way to much and i was wondering if there was any way to actually unlock it to T-Mobile pre paid. I researched all over Google and i dont see any valuable data is just only ADS and FAKE info. Please anyone help me. Back then i used ultrasnow to unlock it on my 3gs. But now things have changed Thanks and Loyal Apple Fan Here Iphone 4 CDMA, Version 6.1.2 , Baseband 3.0.04 Iphone 4s GSM, Version 6.1.2 , Baseband 3.4.02 Thank you Everyone!
