Factory unlocked phone with Baseband 6.15.00 question
Hello everyone, and thank you for reading this. I have an issue with my wife's phone and will first post the short story, then the long and complete story.
Short story: IPhone 3G was purchased jail broken (we didn't know it was jail broken). It was on 3.1.3 and the wifi wouldn't connecto to networks, I attempted to update it to 4.2.1 and bricked the phone. I found a video on youtube detailing a way to restore the phone back to factory specs. I did that, but contacted AT&T and requested an unlock. It was granted, but phone will not connect to wifi. Firmware is listed as 6.15.00
Long story: My wife has had her Iphone 3G for almost 3 years. It was purchased 'unlocked' from a friend in Vietnam. The phone had issues with connecting to wife, and myself having little experience with Iphones checked Apple's website. Some people had luck with updating from 3.1.3 to 4.2.1 and restoring wifi. I decided to give it a try and proceeded to brick her phone. At this point I realized she didn't have a factory unlock as claimed. . . I tried Apple's forums and was told they can't help because my phone was jail broken. I was told the same thing at the Apple Store. So I went to youtube and found this video. How to: Fix ERROR 1015 iPhone 3G STUCK ITUNES-STEP BY STEP! - YouTube
At the end of the video he mentions if you use this method it will return the phone to factory specs, and locking it to it's original provider, and if they are who you use to put the sim card in it and your phone will work. If not to jail break it. I chose to contact AT&T (We have T-Mobile) and request an unlock. It was granted and unlocked through Itunes. The phone will pick up wifi networks, but fail to connect to any, including non password connections. I tried mimic settings under static as well, but it wasn't until I compared the settings to another 3g's settings and saw the firmware was different. Google tells me this is an Ipad base band and will prevent her phone from using wifi, blue tooth, or GPS. Her GPS works fine with my sim in it (hers does not have a data plan). I've seen some methods posted to downgrade to a lower baseband but they require jail breaking aftwords. Will updating to 4.2.1 actually fix this issue? Or do I need to change the baseband separately? If I have to change it separately will it affect my factory unlock?
Thank you taking time to read this.
