Hey, I want to unlock my iPhone 4 but I have iOS 4.3.5, Baseband 04.10.01 and I had tethered jailbreak. I restore it to a clean 4.3.5 state now. I can't downgrade to a earlier iOS because i don't have the SHSH Blobs saved. I was thinking in upgrade it to IOS5. The thing is that the iphone was bought locked to a spanish carrier and im trying to use it in Portugal (didn´t know it was locked before the purchase...) is there a way to start using my phone as an IPHONE instead of an IPOD? Dont wanna loose the GPS functionality (using an ipad baseband...) I'm desperate. Thank you.
